The A.R. Rahman music is trite in places, but features some really outstanding numbers, too, especially the comic "I'm Sorry" number with SRK and Juhi and the kids, and the lovely and romantic "Sona Nahi Nah Sahi."
About the film, just don't think too hard about the plot, or you might fall through some of the gigantic holes. Shah Rukh Khan is perfect as a kid-hating, shoot-first-ask-questions-later cop, and Jackie Shroff is excellent (as always) as his older partner. Juhi Chawla provides most of the comedy with her character.
All in all, Good performances, but dodgy plot.
