The biggest opinion change in film (of your life)?…

Probably my opinion on subtitles. Into my teens I considered them kind of a waste, and watch hardly any foreign films because of that thought. Then I started reading for pleasure and found subtitles increasingly fine to deal with.
Even now most times I’d prefer subtitles to awkward English dubbing.

I don't know tbh.

I don't often have huge opinion changes about movies, but I also don't re-watch movies very often.

Here. I have a genre one. I didn't care much for film noir movies once upon a time. There were exceptions obviously, but now it is one of my favorite genres. 

The first Harry Potter film was released when I was in college. I had zero interest in the movies. For many years. It wasn't until probably 5 years ago or so that I watched them and fell in love with the franchise.

The Usual Suspects and Boondock Saints probably. 

At first watch, both seem goofy, till one delves into them.

Boondock is self explanatory.

Usual Suspects is goofy if one views it as a thriller, or tries to fit it in an action category. Even though the writer claims it was just a fun piece, it's obviously truly the story of five people who thought they could do a better job of being the Devil than the Devil himself (the fifth being the woman lawyer). 

All five (counting the woman) have incredibly spoiled lives with superiority complexes that are impossible to relate to. It wasn't until the third viewing that I realized that the meetings the woman was having were with warlocks in the most elite cult, trying to do "lawyer tactics" to become the new Satan. When Keaton sees her negotiating with the Kaiser's people, it finally strikes him who the kaiser truly is, and that's when you see him really get scared. Satan was willing to sacrifice those pawns in the building on purpose just to show Keaton what evil he would do.

It is only this way in which the movie makes any possible sense. A supernatural thriller. All the clues are there. The writer can deny it all he wants, and he may have done it subconsciously, but that's quite obviously what this is.

I gotta say, I feel the same way. Like you, I still think his movies are very well made, and I do still love Reservoir Dogs and Pulp Fiction, but he's certainly fallen down my list of favorite directors. As I've grown up, I've replaced the likes of Tarantino, Robert Rodriguez, and Kevin Smith for directors like Wes Anderson, David Cronenberg, and Satoshi Kon as some of my all time favorites.

Another big change is I'm less snooty about what movies I can enjoy. I used to avoid goofy comedies just because. But now, I find myself really enjoying them. Every genre has its place and purpose.

Mellow it's good that you're back on here I remember you were on the politics forum for a while.

Great late career performance from Gene Hackman.

I fell asleep in the theater watching Blade Runner (the Director's Cut rerelease in 1992). Now it's my favorite film.

I was kind of the same. I remember as a kid expecting lots of action and was disappointed. Now, I appreciate how thoughtful it is.
