Just watched it, would rate it as Good or 6.5/10 at best. OK for a one time view. There were times when I was looking at my watch although I did like the whole full circle ending (not sure if many would wait 1 and a half hours for it).
The reviews on Imdb are mostly Indian based with the usual hyperbolic titles such as
"A movie we needed, but we don't deserve.",
"Best bollywood movie ever." and my personal favourite
"Hollywood may take lessons from this Indian flick"
Most of the Indians are probably in awe that Bollywood whose usual fare is the kinds of Race 3 etc, could make a half decent movie but there are at least 20-30 Indian movies which would rank way higher in my list. Not even in my top 5 for best Bollywood movie of this year.
