I saw this film in 1996 when I was in an English lesson at school. It as since remained one of my favourite films that I have seen again.
Its a romantic comedy that is not bittersweet. Managing to do something no other film as done. Completely captured the atmosphere of high school and the small problems that being a teenager throws at you.
The dialogue and characters are fantastic and the penguin sub plot is genius...
Buy it now. It may look like a film about football, but thats a very small part of the film. So keep an eye out for it. Its on British TV a lot.
