Not counting low-budget or obvious choices.
1. Small time crooks. Bank robbery front operation turns into a successful factory which turns into a romantic subplot. Meanwhile the ads portray solely the bank robbery aspect, which never happens. We walked out half-way.
2. The Matrix 2. Yes, that's the real title, but I don't care. It was bad. I wish I could erase the memory of it from my mind.
4. Baby geniuses.
Movies that were better then expected:
1. Time Chasers.
2. Clonus (aka Parts: The Clonus Horror).
3. I Accuse My Parents.
