With this one, it's like the "Jurassic Park" sequels. We've seen all the special effects before, so they really need better plot and dialogue to actually carry the story. The plot made little to no sense. They added new characters all over the place, including a bunch of "generic" Decepticons for the final battle, and tried to throw in a huge amount of back story that was left out of the first one. I also agree with the post above that the final battle was a bit anti- climatic. I don't want to sound like a dick because this movie wasn't Shakespeare, but you can have a blockbuster action film with a coherent plot. It's still a fun movie, but I think it could have been better, even though it's about giant robots. I've read that the writer's strike may have really screwed with the timing of this film in particular and I think that's probably true. Hopefully the third one will be better.
