This is a cool, albeit tough topic. My favorite movies aren't necessarily those that I think 'everyone' should see. There's a good movie, and then there's great movies. Movies that move you, or make you think a long time afterwards about the themes, ideas, and ideals. Movies that, for their genre, stand head and shoulders above the vast majority of 'good' movies out there. THOSE are the type of movies that 'everyone' should see. At least by my definitions and standards. I like Robert's way of breaking it down by genre, but I don't have a concentrated enough thought process to do it that way. Movies that I have seen, that I feel that for one reason or another, are transcendent, and films that ANY fan of that particular genre should draw enjoyment from......... Star Wars (original trilogy ONLY) Serenity Hitchhikers Guide 300 V for Vendetta (WAY different than the book, but still good) Alien Aliens (Everything after this was very standard sci/fi horror in the Alien series) Dances With Wolves Tombstone Silverado The Good, the Bad, and the Ugly Once Upon a Time in the West (I love westerns, for the most part) Metropolis Saving Private Ryan (I have a very hard time watching this, but I do watch it. I wouldn't say I 'enjoy' it, but I am compelled by it, none the less) Shawshank Redemption Heat Goodfellas I know I've seen more, but these are the ones that come to mind. YOu know, conversely, there's a few movies I've seen that have absolutely been proclaimed as BRILLIANT or a SPECTACLE, and so I watched them, with high hopes, and came away feeling like.......you know, that was a good film and all, but nothing transcendent. Fight Club Pan's Labyrinth American Beauty. I mean I 'get' them. I do. I understand these films, I just wasn't blown away by them.
