for me the biggest disappointment for the movies are
1. Fear Dot Com (2002) I sat through watching it and wasted 1hour of my life, but because i have a brain i decided to walk out in the middle of the movie.
2. Scary Movie 3 - I thought this was cheap
3. The Ring (2002) I didnt find this scary, i was falling asleep.
4. Oceans 11 remake and Oceans 12 - Thought they where both crap.
5. An American Haunting - This movie was so cheesy and cheap, it was like a remake or something.
6. American Dreamz - It was like watching American Pie & Old School (but those two movies are much better and more funny).
7. Independence Day (Will Smith) I like Will Smith but this movie was so cheesy in so many ways, even though i love the special effects the story i find a bit weak.
8. The Core (2003) again like Independence Day the story is weak, the characters are nothing special but i love the special effects.
9. X-Men 3 - I really enjoyed the special effects but again i thought the characters where a bit weak and they where lacking the story because i felt like i was watching x-men 1 again where they where finding mutants with special powers and telling them how great your powers are blah blah, then again like in x-men 1 in the end something bad was happening and they lived happily ever after, this just felt like the first movie but i did enjoy the special effects.
Thats 9 movies i found disappointing, but worth renting.
