With the appearance of Will Ferrell, I figured this was a big enough episode to deserve its own thread. I can imagine people being disappointed if they were expecting Anchorman-level Ferrell here, and he actually seemed to reign it in a little bit. But I still loved seeing him on there, and liked the episode in general.
I also liked the episode in general. Will Ferrell seemed to play Deangelo Vickers with three different personalities depending on the scene. But I thought it was funny. And I'm on board with Deangelo on this one important point - I could not care less about Jim and Pam's baby.
Erin ruled the episode for me, from her inability to choose how to answer the phone ("I'm so sorry!") to her shaving Michael. "Don't shave my lips!"
Kevin and the return of his hair piece is a close second.
I also liked the episode in general. It seemed like half of it was just putting the camera on Carell and Will and letting them go (such as the entire cold open, or should I say hot open). But I thought he was hilar. He was still playing "Will Ferrell, man who says normal things oddly at odd times," but low-key. And what normal things said oddly at odd times he said.
Batman's training and changing the name of the League of Shadows didn't fundamentally alter the character. This does. Spider-Man and Peter Parker isn't a reluctant hero pulled into service by fate and destiny.
