It is a fun movie, pure entertainment. Don't think too much or sit to analyze while watching it. I loved the comedy and the dailogues. All the actors have done a great job. Just take your set of girlfriends and watch to have a good time.
It got a little boring after the intermission, but soon it was back on pace.
Costumes were good, except the last one that Kareena was wearing (was a little funny). Music was ok. I mean if Amit Trivedi would have given music for the movie, it would have been awesome and totally next level.
Concept of covering different stories of 4 different individuals was good. Just go watch and have fun.
