Finally, an episode of Doctor Who, this season, that I liked. It's about time!
Actually, I did not mind most of the episodes all that much, but what I have seen of this season, so far, seemed, overall, a bit dreary to me. However, the episode titled "42" wasn't bad at all... although it was a bit predictable... but that is a problem with pretty much anything on TV or in the movies anymore.
Perhaps it is just that age makes everything look the same, or derived from something that has already been seen or done.
