I guess my list is a grab bag without any particular theme:
Repo Man
My Life As A Dog
Hannah And Her Sisters
Goodfellas (that might have been the early 90s)
The Unbearable Lightness of Being (don't love this one now)
I liked Spike Lee's movies back in those days.
Down By Law and Mystery Train
Yep, I drank the Jim Jarmusch kool-aid, down to the last drop.
And how tastes change over time: I loved My Dinner With Andre and Sex, Lies and Videotape at the time.
I'm pretty sure I have selective memory about the whole decade, but I know I was just so glad when the decade was over.
Wasn't a big fan of the John Hughes oeuvre, then or now, but I know it played a pretty big part in my experience of those years.
