Transformers

I thought this was one of the best movies I've seen in the past 5 years easily.
I highly recommend this to anyone who watches movies for the entertainment factor rather than reality.

I didn't play with the toys growing up. I can't even recall having one. I watched the cartoons a little bit though.
I think you'll still like it, as long as you go into it expecting it to be based on a childrens toy.
My wife and kids both loved it too.
