Why so much criticism?

Exactly.
Maybe rabid fanboys of 'Global King' who couldn't believe that their God's reign at Box-office is over went upon ever website there is in this *beep* i n g world and spread hatred against the film and Aamir obviously.
This is the only explain I can think of.

IDK. I'm new to Bollywood movies, but I thought this movie was awesome. Very entertaining, great plot, lots of action, and the ending really surprised me. Very good movie that is better than a lot of the garbage Hollywood vomits out these days. Maybe a little too much use of slow motion for my tastes, but a very well written, produced, and directed movie. Now I just have to watch the other two, and I will definitely be looking into more Bollywood films.
