Awesome review.
I'd also like to point out a logical flaw in the movie that still aches my head.
If the whole thing dated back to the 60's, and there was a 'deal' setup between Megatron and Sentinel Prime, then why wasn't this addressed in the first two movies? Did Megatron just kinda forget about it, get carried away with his exploits and then suddenly remember? "Oh wait, I set up that deal ages ago! Time to cash in!" Fruthermore, wasn't Megatron frozen in ice for a lifetime but Sentinel Prime's ship crashed in the 60's... Ow, my head.
