Well I rented the 3D version and watched it last night. I'm shocked that a lot of you seemed to rate this lower than Part 2 and 3. I thought it was MUCH better. No Shia, no Tad Hamilton military team, no belching, farting, leg humping, giant balls or any of that crap. Honestly it felt like a 1990's Michael Bay movie to me. Much more in the tradition of The Rock and especially Armageddon compared to most of the junk he's done from Pearl Harbor to now.
It had a very good cast, no one that I found annoying. Even the daughter and her boyfriend were surprisingly decent.
What's really cool is that it pretty much works as a direct sequel to the 2007 original. In Revenge of the Fallen we are stupidly presented with the notion that the final city battle in the first one was somehow swept under the rug and people don't really believe in transformers. But AoE starts with people pissed off about the urban destruction. A more fitting evolution, IMO. You can just watch TF 2007 and then Age of Extinction and assume that Stanley Tucci got Megatron's head from the bottom of the ocean. Ignore ROTF and DOTM entirely. You can't ask for much more of a palette cleanser than that (minus a full reboot under a new director which would be great but honestly just not something we can get worked up about at this point.)
I felt Age of Extinction had a bit of a 1986 animated movie vibe with some of its early good guy deaths, Galvatron, and a powerful third party enemy in space. I was hoping that the "creators" would be revealed to be those guys with the three faces that would say, "guilty" in the original cartoon. I'm excited to see where Optimus was going at the end of the movie.
The big criticism is of course the freaking running time. Good gosh, I don't know how often I'll ever have the energy to sit through the whole thing. I remember toward the end of the movie thinking back to the early stuff at Mark Wahlberg's barn and thinking "was that really a part of this same movie, I feel like I'm watching a trilogy marathon," lol.
Anyway, I thought it was fun and harmless check your brain entertainment. Not on par with the great summer films we've gotten this year of course but probably as good as we could have hoped for from Bay.
