Dum? Well the movie starts with loads of entertaining dum with good foot tapping music and few good looking people attached to it. It's only since the pre-interval the movie starts to wobble a lot leading towards a stupid and weak climax. It has a lot of hangover of 'DDLJ' but does not do proper justice to it. So on an overall basis, would sum it up by using the popular nursery rhyme where after a Humptyfull (entertaining) ride has a great fall where none of the kings men (writers and director) could put Humpty back to track again.
