I see some of the reviewers here describe this as a parody of or satire on Bollywood musicals. Having seen nothing of Bollywood except a few music clips, I can't talk about that. I have to take this movie at face value, and on its face this is a moderately diverting musical with a few good moments amidst too many rather drab ones.
The story is somewhat interesting, the character of Sue, who fulfills the role of shaker-upper-of-things is quite appealing, and some of the musical numbers are pleasant (surprisingly, no one sang in that helium-junkie pitched style the girls all seem to have whenever I see clips from Bollywood musicals, although I don't know if this is because they were trying to make the movie more appealing to the west by having a more western-style voice singing these Indian songs or whether that high-pitched voice isn't as common as it seems to be). But the movie feels underdeveloped (even though I found it a little dull, I still felt it needed to be longer to flesh itself out) and most of the characters are overly generic (except for the grandmother and Sue's father). Ultimately watchable but nothing more, unless you're a fan of Bollywood films in which case this may work on a whole different level I don't see.
