Not much to say really, overall I thought it was good but a lot of it I didn't like, verging on hating.
The action sequences were phenomenal but I found a lot of the humour in it to be really stupid. Need I mention the "tooth fairy" remark? Also there was Optimus Prime's face...I mean he looked like he was talking out of his chin! They should have kept to having him have the full face mask thing like he had in the G1 days IMHO.
At the end there was understandably plenty of room left for a sequel and if there is one I saw more robot fights and less people!
