Went in with a lot of skepticism. I really didn't enjoy any of the trailers and was expecting to be pretty underwhelmed.
I was so happy to be pleasantly surprised. The animated version was one of my favorite movies as a kid and I was not disappointed. They've made a really excellent film that pays homage to the original without trying to be a carbon copy.
No one can be Robin Williams except for Robin Williams and though I was pretty disappointed at first with Will Smith's casting, he was actually pretty great in the role. He was able to make it his own without attempting to fill shoes way too big for him. I was most surprised by his funny and nuanced performance.
I highly recommend it. See it on the big screen.
