Idea...Marvel fans review JL here

Agreed. I rate it 9/10. The IMDb rating is 8.1/10. So the majority of people consider it a really good or great movie.

Overall, I thought it was fantastic. The character dynamic on the team was outstanding and the action sequences were pretty snappy as well. The first maybe 1/3 of the film felt rushed, quickly introducing the characters and hastily throwing them together. Steppenwolf in Atlantis, with the Amazons, etc. Just a lot going on with very little focus. And I really could've don without the classic Snyderism on display in the film's opening; a gloomy song accompanying a montage of hate and hopelessness. Luckily it moved away from this tone quickly and never looked back.

Going in I hoped to be pleasantly surprised; and it exceeded my expectations to say the least. Its biggest triumph being that it moves away from this awful 'grim & gritty' Snyder tone and breathes life into the dark and spiritually empty DCEU. Superman felt like Superman for the first time in this current iteration of the character. Finally, the heroes actually wanted to be heroes.

Affleck was solid, Cavill got to smile for once, and Gal just kept doing what she's been doing and nailing it. I've never cared for the Flash one way or the other, but this lovable goofball version of the character really worked for me. I don't know how true to the comics Aquabro was, but I dig him. And of course you knew JK Simmons would make a good Gordon.

Maybe the biggest surprise for me was Cyborg. Another character I don't have a ton of experience with, I was expecting him to be generic as hell. I mean he's a cyborg named Cyborg; and the character concept screams 'token black guy.' "I know DC has better black characters, why didn't they use one," I thought coming in. I couldn't have been more wrong. He was perhaps the most nuanced character in the entire film, and even though he could be brooding at times, there was a humanity to him that felt genuine for a movie character. He laughed, he was blunt when communicating; he was honest. He was real. I'm not familiar with the actor either, but whatever they were looking for with this role, I now understand why they gave it to Ray Fisher. He crushed it. The biggest compliment I can give JL is that coming into it I had no interest in Cyborg or Aquaman and now I would absolutely watch either of their solo films.

The movie isn't perfect. As I said earlier, it's all over the map early on, but cleans up nicely down the stretch. The resurrection of Superman comes about all of the sudden and happens so quickly it doesn't feel entirely earned. That being said, I wouldn't want them to devote a 45 minute side quest to it during the film so this was preferable. And the battle that followed was comic nerd bliss so no complaints there. (though I will say one reason I was never a huge Supes fan was on display in the fight sequence. The guy is a one man wrecking crew. He can do everything they can do and then some, there's no point to a team when one character has such a ridiculous power set. I'll touch on this again in a minute.)

The villain is bland, but no different from 70% of comic book villains, so no harm there. This is the heroes' story, not his. He at least felt like a credible threat until Superman joined the fray. I had to chuckle at the writers when they had Superman mop the floor with Steppenwolf and then decide to go help civilians, essentially because if he sticks around the movie is over. I mean Supes laughs the guy off upon his return. "Is this guy still bothering you," as he pummels Steppenwolf without breaking a sweat. And considering Clark has literally just returned from the dead, the audience knows he has the thickest plot armor in history, even for a comic book franchise film.

Other nitpicks include Bruce being a prick to WW for no reason. I don't see how insulting her dead boyfriend is supposed to motivate her to lead or whatever. Flash is injured in one scene (he had to be dragged out by Batman) and then starts zipping around the Batcave in the very next scene as if nothing happened. Various characters refer to Bruce as Batman in front of strangers on the street, multiple times. There are a few other minor things that didn't quite add up, but no more than any other film.

But again, the good far outweighs the bad here. It was everything you want from these characters in this type of film. The negativity surrounding it was warranted before it was released, given DCEU's track record. But now that we've seen it? Look, I was probably 90/10 Marvel/DC reader as a kid. I didn't dislike DC, I just got into Marvel first and only had so much time (or budget) to play with. I prefer Marvel movies because of my affinity for those characters and the studio's understanding of the material. They know what fans want to see. Up until recently, this clearly has not been the case with the DCEU. But they've finally figured it out.

Is Justice League as good as the Avengers? No. Did I enjoy Thor Ragnarok more? Yes. But there's no way Ragnarok is a roaring success and Justice League is a failure if we're judging by the same metric. I simply do not understand the negative response to this film. Ragnarok is not a 90+% film if JL is a 40% film by the same metric without some kind of bias at work here. People have been burned by DC too many times and expected a failure, so a failure is what they saw. It's a shame what's happening here.

My biggest concerns regarding JL have nothing to do with the movie itself. 1. With how amazing and flat out fun JL is, I don't see how you can watch it back to back with MOS or BvS. You just can't do it. The central characters behave so differently (and for the better) in JL that you would think they were replaced by body snatchers or something. All the negativity is wiped away and these guys get back to helping people and feeling good about doing it. (Though I do appreciate Bruce's admission of guilt in JL regarding his sins in BvS. The audience needed to hear that to completely buy into this happy go lucky Batman, I think.) The audience can't pretend those movies didn't happen because the JL script heavily leans on those past experiences, so you're on your own when it comes to reconciliation between drastically different tones from film to film.

My other concern: The DCEU screws the pooch again and makes another radical shift (this time for the worse) if JL underperforms (in part due to these bogus reviews) at the BO. WB/DC: You got it right this time! Please don't go back to Snyderville where every hero is a self-loathing, cynical maniac completely devoid of any emotion beyond spiteful anger and contempt for humanity.

So yeah, JL was excellent. Every hero (and their corresponding actor) brought something to the table and made DC superheroes fun again. I'd go maybe 7/10 despite its flaws because the stuff it got right it really hit out of the park.
SPOILERS: Hell, I even enjoyed the Luthor cameo in the post-credit scene. He was easily the worst part of BvS so I'm glad they relegated him to clean up crew on this film-- but it's good to know there's evil brewing here at home, not just an endless parade of space gods to contend with. His appearance also felt like a Pit-Bull video; bald dude on a yacht just chilling.
