I thought the movie was awesome, but there were a few things that irritated me about it;
1.) No background on how Megatron went from a Jet Fighter in the first two to an 18 Wheeler in DOTM, and how he wasn't in the movie very much.
2.) The ending seemed to come outta nowhere and it happened 5 minutes before the movie ended.
But that's about it, other than that I loved it!!!!....But I think the first one was still the best one.
