The Last Airbender, a movie about a kids show. The kids showing being really good, mixing story and action together brilliantly, and the movie bombing into the ground with lots of CGI, crappy dialogue and no story.
Don't watch this one folks. Know a few of us were looking forward to it, but just don't.

Also, the video review is in the Rottentomatoes show. Couldn't find any video's that primarily reviewed only said movie. But it also reviews Twilight in a negative way, so yay.
