CC2C wouldn't disappoint anyone who goes to watch it for sheer enjoyment and a break from the daily routines. If you go for it looking for sense, then you'll end up criticizing this movie.
Akshay Kumar doing what he really is best at. His comic timing in the movie was great, Ranvir Shourey was good but seemed neglected towards the climax ... Deepika Padukone in her double role looked nice and acted fairly well ... Mithun Da (Akshay's father-figure) acted well but the role was pretty short ... Gordon Liu and Roger Yuan were also impressive ...
The plot was great but a bit more could have been done with it ... One thing that was a bit strange(and good) was that the climax wasn't too stretched; short and sweet ...
All in all, if you want to take some time off and are looking forward for a good laughing session, go for it ... If you seek sense, this one's not for you ...
