oh for heaven's sake! This is a movie that sprung from marketing toys. It doesn't pretend to be momentous science fiction. It's just action from beginning to end. I thought getting Sam to OP at the end took WAAY too long but other than that, it was a pretty good summer movie. But then, I never played with transformers or watched the tv show so I had no canon expectations beyond the first movie. If you just like action movies you'd probably like this one.
Except all of the good action movies have decent stories and characters in them -as well as something of a plot- The Lethal Weapon seires, the Die Hard series, the Rambo series, the (first two) Terminator movies. Just to name a random few.
It doesn't rape you in the ass with nonsense for an hour straight with a bunch of characters you don't give a shit about nor treat the titular characters as secondaries.
Even as a Summer Action movie this one fails.
