Norbit is the film that lost Eddie Murphy his Oscar.
It's actually not as bad as that. It is not good, but as a stupid American comedy of its ilk, it is one of the better ones. Amid the scatology and grotesquerie, there are a some sharp lines, the character of Norbit is very likeable, and the actors deliver.
I don't recommend it as such, but I had to say that the reputation of Norbit as irredemable is exaggerated.
The only reason I saw this movie was because my mom and sister's boyfriend were watching this together once when my sister and I came home from the store. It was all very weird... Glad it happened, though. Memorable experience to witness it all.
