I saw it and was actually surprised at how decent it was. Its not a great movie, but its not terrible either.
Im not really a fan of the old TV show(ive seen maybe 2 episodes in my entire life) but the person I was with who is a fan seemed to like it alot also. Will Ferrell is pretty funny, if you like him and his movies you will probably like this. There are some pretty damned funny "Will Ferrell" moments akin to something like Anchorman or Old School. Nicole Kidman is freaking hot in this too. Dammmmmn!
