Clerks (1994)
This might be a divisive choice, but this debut film from Kevin Smith is what I put on when I’m bored on a Saturday afternoon and want to watch something. For a a film that’s done in black and white (because it was cheaper), done on a shoestring budget, and shot at the convenience store that Smith worked at, it’s really good.
There’s something about the DIY sensibility, crass humour and frank understanding of the zeitgeist of the slacker generation in the 90’s, this one is one hell of a cult classic.
