It's been less then 24h I came out of the cinema & I'm still stunned by it.
That was the best 3D experience I had after "Avatar" - just awesome.

I pretty much loved every mismatch to the old one and I am surprised how the writers pulled out this great new perspective on quite the same story.
I was very sceptic about Andrew Garfield when I heared he was casted but I think he did an amazing job. Was he a better spidy then Maguire - hmmm it depends... each one has his advantages, so it really up to you.
But as @MajorMercyFlush already wrote (great review by the way) the new Spider-Man is more dark, also he is more direct, more offensive & less sensible.
I was blown away by the movements and the incredible CGI of the Lizard also the humor was a great combination and I think it fits the original Spider-Man animated series very well.

Oh yeah and I loved Emma Stone - she is just one of the reasons I love the new Spider-Man more ;)
