Much better than expected (perhaps this is because expectations were low). Great cast, lots of laughs. Actually enjoyed the plot as well. (Anything with Jack Black and Ben Stiller alone is worth some laughs, but combined - look out!)
Good but not close to great. Quite a few laughs, but not a good film overall. If you like Ferrell and Reilly and Judd Apatow's writing then you'll laugh a good deal. But it's not a very memorable flick in the long run.
