Awesome, awesome movie! It was pretty much everything that I thought it would be...VERY loud, action-packed, funny, and MORE TFs (of course)!
Starscream: I have REALLY warmed up to the movie-verse Screamer so much...I do adore him. In ROTF, he goes back to his G1 roots, which leads to some great interaction between him and the resurrected Megatron. And, he gets more screen time than in the first movie as well as more dialog. I do have one nitpick, though, and that's his voice...there's a noticeable change, but why? I liked the sound of it in the first movie better.
Ironhide: He has definitely become my favorite Autobot...something about him... :wink:
The Fallen: Unnecessary...movie should've focused around Megatron's return to power and plot to defeat Autobots/claim Earth.
The Twins: Take 'em or leave 'em

Soundwave: Again, should've been more of him and less of this 'Fallen' character. The voice threw me off, Frank Welker did the Dr. Claw voice (anyone remember Inspector Gadget?). I realllly wanted vocodor voice...that's the only SW voice I've known (and loved)!
Devestator: BIG EFFIN' BEAST! Amazing CGI work on this bad boy. However, like the Fallen, Devs is just underwhelming in this movie. This should've been primarily a Megatron is revived, bickers w/ Starscream, plots domination of Earth/Cybertron...oh well, again...just my opinion.
Jetfire: Wow, an SR-71 Transformer...COOL! Old-age evident and mannerisms...brilliant! Then taking his own spark (life) and Optimus Prime utilizing his parts to battle Megatron and the Fallen...WOW!
Optimus Prime: What can I say...he's the MECH, though I was never a huge fan of OP, he does good in this installment.
Ratchet: Why no love for everyone's favorite medic? He gets less screentime than the first movie!

Sideswipe: Definitely not enough of this cool cat! MOER PLZ!
Sideways: Can a 'Con get killed off any quicker and unceremoniously?
Ravage: AWESOME! Hunting and stalking like a big cat should!
Bumblebee: Sappy at first, then turns into KILLERBEE at the end...yikes?

Humans: Ok, ok...they're essential to the story and all, blah blah blah.

Again, ROTF was in-freakin-credible! Had its ups and downs, but overall a 8/10! I expect this movie to break some box-office earnings records and to stir up the fans (Ha, already seeing some ROTF art on here...and I'm getting a fanfic muse XD)!
