The Basketball Diaries (1995) 
I watched this a lot when it had first come out, I had it on a VHS tape, probably ex-rental. I've not watched it since I got a DVD player and donated all my tapes!
Man, does Marky Mark almost ruin this film, the boy could. not. act. Lucky for us Leonardo DiCaprio and Juliette Lewis are on fine form. However, the film itself is ultimately a massive downer, heroin stories are not fun, all cold sweats, scabby faces and puke and piss stains!
That being said, it's the first time I've seen the famous 'school shoot out' dream sequence, that bit was snipped by the censors in the UK back in the day.
