Peter Suderman agrees with me that it's the years' most overrated movie:
Slumdog isn't a terrible movie, but it's sappy, suspense-free, and packed with one-note characters, including a female lead who's more object than person. In terms of violence, it's grittier than most similar pictures, but mostly in a desperately "edgy" way that seems designed to gloss over its blatant sentimentality. The best you can say about it is that it's stylish schmaltz.
