Hate the Flashlight Song
I don't get how that was seen as so good that it became produced and a part of their final performance. It was generic crap. It reminds me of that Friday song, a lame attempt at a pop song that is bad enough to be entertaining.
Why does it always happen when there needs to be a piece of art as a central part of a movie--that's created specifically for that movie--it usually isn't very good?
