Roger Ebert's Worst Reviews
Someone actually took the time to list and write a response to what they think are Roger Ebert's 75 worst reviews ever.
There's some good fodder for arguments here.
FYI Ebert actually posted this on his Facebook and Twitter accounts and agrees with guy on some of his points.
Surprised his Avatar review isn't on the list... Avatar sucked so hard once you got past the pretty visuals, Ebert apparently never did... He even compared it to Star Wars
