Remember the episode where Desmond was first revealed as the man in the hatch? Or when he traveled back in time to England to help Daniel with his experiment? Sure you do as Desmond has been at the forefront of some classic episodes of the show. While parts of this were good, this was definitely not a classic and not one worth immediate rewatching.
We did not get any Ben Linus, Locke or Sawyer fixes tonight and we only saw Jack and Hurley briefly. I understand that not every character is needed in every episode, but I would've liked to see something else going on other than Desmond's storyline which wasn't all that great to be honest.
Save the insane machines for Fringe, JJ Abrams.
