Well, went and saw it last night. Yeah, it's probably my favorite one so far. More transformations (including bot to vehicle, which didn't seem to happen as often in the past three), a decent enough plot, cool villains (Lockdown and Galvatron), LOTS of screen time for the Autobots, complete with stand-out personalities and looks, good enough humor at the right moments, spectacular fights, not a bunch of unnecessary crap, etc.
This one actually seemed to have a bit more emotion to it as well, which I liked. I genuinely felt bad when
Ratchet died, and Optimus was clearly distraught over it, and the deaths of his other Autobots, unlike when Ironhide died (since his reaction wasn't shown, on screen at least), where nobody seemed to care. Or the unforgettable "Aw, Jazz...". lol
Optimus' portrayal in this, I thought I wouldn't be too keen on, but I happily stand corrected. Optimus' anger was understandable. All this time protecting and fighting for the humans, and what do they do? Stab him and his Autobots in the back by hunting them down and killing them, relentlessly. Not to mention Sentinel's betrayal, and all the loss he's suffered, and death that he's been surrounded by. Optimus, and the rest of the 'Bots for that matter, were quite jaded in this. But, at least the 'Bots seemed to have renewed vigor by the end of the movie. The movieverse Prime is easily one of my favorites now, within my top three (as #3). I liked him before, but not enough to rank him that high.
Also, I LOVED Hound. Aside from obviously favoring Prime, he had to be my favorite Autobot. Also, I definitely liked the character of Cade Yeager much more than Sam. He was helpful, fairly mature, and actually helped renew Prime's faith. So all in all, it's still not perfect (no movie really is), but it was a pretty entertaining and fun ride. I definitely recommend it to those who haven't seen it yet.
