I just watched it this afternoon as I couldn't stay up last night. I've been looking forward to it and it was great. I totally lost it when the first sketch, Conan running to LA, had him stopping at the Victorian Doll Museum.
The Universal tour was awesome, like when Conan riffed on the Psycho part of the tour. And Will Ferrell's opening was good too as it did seem like Conan had no idea that was coming, truly caught off guard.
But best of all, it didn't feel like a different show with different humor. I doubt we will see Masturbating Bear or Pimpbot, but it didn't feel radically different.
