anything made by Disney
Tron was epic and was made by Disney.
As far as what I think was the worst movie that I had the misfortune of watching was Hostel. It started my absolute hatred for how horror movies have evolved these days. Nothing but shock and gore. No story, no plot, just hundreds of different ways a person can be brutally and painfully mutilated or slaughtered. I find that utterly boring. I like horror movies that scare you stuffless with suspense before anything even happens.
But I'm just an old man set in my ways. First time I saw Jurassic Park back in theaters in 94, I admit, it was a hokey movie but the suspense kept me riveted.
