So I finally bit the bullet and caught this last night. It wasn't "that" bad.
Let me see if I can sum it up. The entire problem with this movie is the bad stuff received more time than the good stuff. There honestly was some great moments in this film. Unfortunately, there was just too much mind numbing human stuff. They could have easily taken this move from D+/C- level to a decent B grade by removing 45 minutes of human crap. The daughter, boyfriend, Daddy issues was scripted horribly. Outside of that, Marky Mark did very well. Maybe because he followed Shia Lestupid but I liked his role in the film.
What I didn't like... Galvatron and the human created robots flew through the air like some sort of nanotechnology you see in other films was ignorant. They should simply transform. Galvatron was either introduced too early or not used enough. If they were going to play the Galvatron card as they did in the movie, they should have simply had him light up at the end and the screen go black. Instead, they teased him a couple of times and it was completely wasted and overshadowed by everything else. Also, I don't want to hear anything else about there being no robot forms of the dinobots because they did transform.. twice I think... and they looked great! It was just really sad they were not used enough. Outside of a couple of stampedes, it was completely wasted. Grimlock in robot form looked as if he deserved some serious screen time killing stuff. Other than those couple of things, everything was minor Michael Bay, plot hole, ignorance. Rather minor but every now and again you sat there and wondered why they did things the way the did...
What I did like was Optimus. He was very well done. He suffered from a little bit of Michael Bay directing but his fights and everything else was solid. The other Transformers were great as well. We just needed more. I still think they made a mistake killing off some of the guys in the previous films. It would have made for a much better serious to have more and more Transformers and Decepticons accumulate over the series for a much more climactic moment but they have sacrificed so much over the series it is as if you get 3-4 on each side and that's about the max. Starscream and Ironhide should both be alive at this point. Also, welcome back Frank Welker. Yep, that was a nice touch.
Overall, I don't know how Michael Bay watches these things and makes the calls he does. He honestly has pieces of a great movie. I think someone should take over and build from this one. There's enough there to make it work. You have Optimus, Dinobots, and Galvatron so someone should be able to walk in and begin printing money. Grimlock needs to speak next time as well.
If you go see the movie, take a 30 minute nap somewhere in the middle and you'll have a great experience. If you suffer through the whole thing you'll be asking yourself and possibly yelling at the screen "Why?!" several times. Other than that.... I think it is the best of the series it's just too long for no reason.
