After watching it last night I need to add Gregory's Girl to my list (I think it has been mentioned on this thread before). I never watched this before because I thought for some reason that I wouldn't like it, but I did.
It is about an awkward teen who fancies the girl who joins his school football team, but really it is about all the small, ordinary and bizarre elements of teenage life.
It reminded me of my favourite film, Show Me Love (but obviously, Gregory's Girl came first...) in that it was both funny and true. I liked the incidental things, like a penguin wandering the school corridors, or the headmaster playing the piano. Other things that I was reminded of were the tv show Teachers and films like Billy Elliot and Napoleon Dynamite. So if you like any of those, or even if you don't, you should watch Gregory's Girl.
The only thing which stops this being a really great film is the lack of any stand out visual style, but as a film about teenage life it is hard to beat.
