Forget what the naysayers reviewed. It brought me back to my childhood. I thought it had a good enough plot. Action was outstanding, and Optimus Prime's voice is the same as when I was a kid some 25 years ago. Those bits of nostalgia coupled with modern day CGI fulfilled this geek. And what were you expecting Shindler's List? L.A. Confidential? The first time you saw Sixth Sense? It's mindless fun and this fanboy was all for it.
Output:
Positive
