There are sooo many but here's what I can think of off the top of my dome:
- The Bourne Ultimatum. Don't get me wrong, still a good movie, but I just thought Identity and Supremacy were much better movies. There was like 1/10th the action in Ultimatum and way more story which to me isn't what the Bourne movies are about.
- Transformers 2. Just a horrible movie. I had no expectations for Transformers 1 and it turned out great, but the sequel was just brutal.
- Iron Man 2. Brutal movie, the first one was great, but the 2nd one was lame as shit.
- Indiana Jones 4 (The Crystal Skull or whatever). I don't even need to explain this one, just a horrid movie.
- Daniel Craig Bond Movies (Casino Royale/Quantum of Solace). Took everything good about the Bond movies and threw it away. Instead of cool gadgets, witty humour, hot babes and car chases, we got 2 hours of poker scenes in Casino Royale. Quantum was slightly better than Casino Royale, but still not on par with the other Bond movies. I'll still watch Bond 23 but I'm not expecting anything good.
- The Phantom Menace and Attack of the Clones. Both brutal movies. Thankfully Revenge of the Sith was good, but the first 2 prequels were bruuutal. Phantom Menace is literally unwatchable.
