This isn't a very ambitious movie,but I enjoyed it. I didn't enjoy it a lot, mind you, but I did like the scenes where they mocked the exposition you usually get in music biopics ("...because I'm George Harrison, of the Beatles.") I'm kind of getting tired of the whole Judd Apatow scene, though.
The music was quite good, but it was just authentic-sounding. It didn't have that extra edge of also being funny, like with the Rutles or Spinal Tap. I realize those are tough comparisons, but that's what you get when you make this kind of movie.
Also, I was kind of disturbed by how how Jenna Fischer was. Pam would never dress like that!
