I tend to re-watch more movies than movies I see for the first time and it's been like this every single year since I have been keeping track which is basically 2012 to date with 2017 being the exception (although 2012 was VERY close to being in favor of first viewings as there was only a 1 movie difference in favor of re-watches).
or I could say this... if I rarely re-watched movies I would largely lose interest in movies as a whole as re-watching movies helps ensure I get a solid level of entertainment from them as without re-watching I would be stuck to largely seeing movies that are forgettable since I feel I have largely exhausted seeing movies from the past that would be of any real worth for me (although movies that stand out I still stumble into here and there into the future). because while I think there could be some undiscovered gems from the past that I have not seen, I would likely have to watch a bunch of forgettable movies to 'maybe' find a gem which is why I am in no rush and I just watch whatever I watch and whatever happens, happens.
but if your excluding re-watches and looking at seeing movies for the first time only... in that case it's largely new-ish releases at this point in time even though I do venture into the past here and there. but I don't really have any precise system when it comes to deciding what I want to see for the first time as if something looks interesting enough etc, ill probably give it a shot. I just stumble into stuff on IMDb and other websites etc here and there, or maybe an occasional comment from some users around these IMDB2 forums etc.
but at the end of the day... since most of what I see are re-watches, in that regard, I usually just decide as I go along in many cases although for movies I consider to be among my favorites, and thereabouts, I typically re-watch these a minimum of once every few years or so. but I still try to re-watch movies I mildly like (i.e. 6/10's) here and there to mix things up.
p.s. I rarely see movies on standard cable/satelite type of TV as nearly everything I watch is almost always going to be from a proper source.
I think it's at least partially because your more easily pleased with the typical Horror movie than a wide range of IMDb users are. because, at least in my opinion, for a genre that's fairly popular, like Horror seems to be, it generally pretty weak overall as that seems to be a genre people default to in a attempt to make a quick buck.
or look at it this way... for a genre that's popular with us males, I tend to see Horror to be pretty much the overall worst or close to it (although many comedy movies are pretty weak come to think of it and these seem to be pretty popular to(still, I got more movies listed as Comedy among my favorite movies in general than I do Horror movies)).
or another thing... I think Horror movies primary appeal is mainly with young 20 something males and younger, or thereabouts. because I think why many Horror movies don't score high is when comparing them to ALL movies in general, not many are of any real worth.
but with that said... I definitely agree that some movies are scored WAY too high as many score into the 7.x/10 to 8.x/10 range that are pretty average-ish. a recent example... Parasite (2019), which has a 8.6/10 average, which is sky high and that movie will likely be forgotten in the not too distant future as it's simply not got enough mass appeal to be remembered like true classics are etc that people still talk about in 10-20-30+ years.
but one last thing... I don't have any restrictions or limitations against Horror movies, it's just that genre is quite unlikely to output anything of any real worth with fairly rare exception. because when I rate movies I ALWAYS rate them in relation to everything I have seen as movies I enjoy as much as I can enjoy a movie get a 10/10 and things scale back from there with a 5/10 being what I consider a average movie (like in terms of my overall interest in it) which most movies I have seen score a 5/10 (Thumbs Down). so while about 80% of all movies I have seen get a Thumbs Down, I would say at the very least most of what I have seen in total was decent enough not to have wasted my time but since I ultimately judge my basic Thumbs Up vs Thumbs Down based on whether I want to re-watch it or not, then only about 20% of everything I have seen gets a Thumbs Up.
moviemouthYeah, which is pretty much young males (i.e. 20's and younger for the most part) in my estimations.
because when you think of a typical horror movie it's usually some gore/slasher, or jump scare type, which are a dime-a-dozen.
Johnny-Come-LatelyIn my experience based on IMDb's average rating... if something is not at least a 6.x/10 or higher it's unlikely to be of any real worth although there is some rare exceptions for me.
but with that said, I tend to roughly translate IMDb average scores like this in terms of wide opinion...
4.x/10 and less = crap
5.x/10 = mostly negative opinions
6.x/10 = mixed-opinions
7.x/10 = mostly positive opinions
say about high 7's on up (i.e. 7.5/10+) are the more praised movies.
but I do think it's getting a bit easier for some movies to crack into the 8.x/10 lately as I think some people hammer 10/10's on certain types of movies a bit too easily.
but with that said... another way to roughly gauge a movies worth, is not strictly by it's IMDb average score (since some more obscure movies can be scored a bit too high but only have say 20-50k votes) but I think volume of votes can be a rough indication of a movies popularity paired with IMDb average score as that might be a rough idea of whether a movie have a chance to stand out or not. because I figure in general... if you got a wider range of people scoring a movie and it still scores high, that movie is more likely to stand out in general.
just some random thoughts

; nothing concrete above but I do think that whole IMDb score/total votes combo is a bit better than strictly looking at a movies average score.
Raimo47While I tend to agree comedies are largely a dime-a-dozen to (like the Horror genre is) there are some gems here and there especially if you don't strictly stick to straight comedies and find ones that have a solid balance of drama/comedy. but with that said... there are not many that stand out although there are some that score strongly for me to rank among my favorite movies in general.
with that said... between serious movies and comedies, serious movies are far better overall. so it's pretty safe to say we agree in a very basic sense.
