Old Wine in new bottle.
This movie is a rehash of the typical bollywood movies we have watched in the previous two decades. There is nothing new or exciting. For whiling away 3 hours, it is OK, but I don't see why critics are going gaga over it. SRK factor I guess. Not even the best SRK movie - but watch it if you have nothing else to do. Not as good as the reviews make it out to be, just like Sawariya is not as bad as they say.
The much talked about 70s part and jokes are also not that great. overall an OK movie.
