Blade: If it weren't for the nice action scenes, this movie would be terribly cliche and unsatisfying. Also, Wesley Snipes is a bad actor.
Seriously, it's filled with cliches: The hero's friend gets shot to death, but still lives to tell the hot chick was taken by the bad guy, there's a giant ceremony involving a big pillar of lightning/energy that shoots through a temple, and the ceremony includes sacrifices from 12 or 13 or 7 or whatever.
Also, any movie who mentions prophecies and "chosen ones" immediatly has a terrible plot. (I'm looking at you, Star Wars)
The Bourne Supremacy: Am I the only one who looks at these kind of movies and say "Wow. Amazing: one guy, walking. BOOOORING". Also, the idea of a coup against an old agent (who always seems to have had a terrible experience in a mission years ago) to set him up so the "evil" CIA/NSA/FBI boss doesn't get blamed for a certain crime has been done to death.
Shrek the third: Burn it and forget it ever existed. Seriously, this movie sucks.
The Day After Tomorrow: The first part where tons of different over-the-top disasters happen and lots of people get killed is nice... the rest is a lot less entertaining.
