I do not like a lot of things like first half seemed a bit slow some scenes were quite unnecessary and dragged the overall duration of the movie. Dialogue writing was poor. Action scenes could have been better. For eg in the Varanasi scene when Ranbir jumps from 1st floor to save Alia, instead of jumping straight or in an arc to make it look natural, it totally seemed like he jumped with a harness, the landing made it very clear. I watched the movie in Inox in 3D. In some scenes when the focus was on one person the other people were too blurr to think they were there it was a technical mistake.
Movie is good and watchable
You can prefer theaters for 3D and a better experience as tv/phone/ipad or won't do justice with the cg and VFX in this movie. Or just wait for 16 September when tickets will be of 75INR.
