Titanic ... by far. One of the worst films ever. "As Good As It Gets" or "L.A. Confidential" should both have come in ahead of that lump of poo.

Also ...

Forrest Gump ... that movie got a monstrous eye roll from me also. I would have preferred Pulp Fiction, or even Shawshank at the time, although I'm pretty sick of it now.

Dances With Wolves ... this movie was ridiculous ... hey how about "Goodfellas?" I guess it split the "mafia" vote.

Rain Man ... supposedly this is supposed to be a great movie, but I find it completely boring. My attention wanders off every time I try to watch it. Dangerous Liaisons would have been a better pick in my opinion.

And that's as far back as my opinion will go because before that, I either agree or was too young or nonexistent to understand the context of the films in their times.
