I just saw this movie, last night at the Drive-In. While I actually managed to have a good time, even though the movie wasn't great, there were certain things about it that got on my nerves. It's already been mentioned here, but I can't believe that there wasn't at least a throw away mention of Galvatron, being that that was a major plot point of the previous movie in the series. Also, Grimlock seems to disappear for major portions of the movie. It's like with the addition of all the King Arthur stuff, the writers had no idea what to do with everyone. Speaking of which, I was actually surprised to find that I didn't hate that part of the story like I thought I would, but they weren't entirely successful at bringing it all together, either. Another area where the movie comes up short is the new Decepticons. While their designs are visually more memorable than the ones from past movies, most of them in this look and act ridiculous. Megatron would be an exception to that. He does look pretty cool. Most of the Decepticons' names in this (except for Megatron and Onslaught) are ridiculous too. One final observation: I wish they would have used the Quintassons in this. I guess naming the character Quintessa after the Quintasson's home planet was a nice homage, but the change also illustrates how these movies love to change things from the mythology, just for the sake of changing them.
