I tend to dislike film snobs, not because of the films that they watch but because they moan about popular films. I have a couple of friends who have a huge selection of foreign art house films and are constantly telling me to watch them because of the political undertones or the in your face irony of the entire film "if you just think about what the director isn't showing you" kind of things. This doesn't strike me as good directing but apparently it is groundbreaking.
I am not a purist though who only looks to Hollywood. In all fairness I prefer underground and foreign films because they tend to show what they want as opposed to cutting the films down to 12A/PG-13/[Whatever it is in your country] standards. Unless the film is improved because of the cuts (I prefer the theatrical cut as opposed to the directors cut of The 40 Year Old Virgin and Donnie Darko) then I am completely against this.
I prefer my Chan-Wook and Fukasaku films to Spielburg and Abrams but I do not believe that this makes me a snob because I can admit that I, on occassion, want to be wowed by explosions and paper thin plots. I primarily see films as a form of entertainment over any form of expression. I will not watch an arthouse film, not matter what the message it is giving, if it is boring whilst I will also quite quickly turn off the latest Hollywood blockbuster if I find the action/suspense/whatever unappealing.
Last point. One thing that does annoy me though is America's tendancy to remake everything to make them better. I was sat near my housemate the other day who was on the Internet and a trailer popup came up for 'Quarantine', we watched it and he said that it looked pretty scary. I immediately said 'That is [REC]', I went to IMDB and within one year America have in fact remade [REC]. Whilst I admit I haven't seen it yet (Live in UK) I will most likely go to watch it to see if it can live up to [REC], I think it is very poor of America to have remade a film after one year. I can accept films that are 20+ years old because they can at least weakly justify it as better effects and methods in which to film it.
Please don't see me as a snob, I do in fact like many of the remakes I just find it poor of America to be constantly remaking films that do not need to be remade. My one defining dislike to film snobs is that many refuse to even watch a remake because it is a remake, but still find it completely acceptable to ***** and moan about how terrible it is.
