After a big, emotional episode like last week's "The Girl Who Waited," it seems like "The God Complex" was in a bit of a lower key. The story was okay, but it seems like Toby Whithouse and Steven Moffat cobbled it together in order to lead up to the end, which is a major plot point in the story arc. This series has had its fair share of standalone episodes, where the story has nothing to do with the overarching plot; and that's fine. That's what Doctor Who is famous for, little science fiction diatribes that all link together.
But this story seems forgettable, if not for the ending and the look deeper into the Doctor's and Amy's characters. The technical work was, of course, beautiful; camera shots looking straight down a spiral staircase, a giant minotaur roaring down a hotel hallway, special effects giving the illusion of a creepy 80s hotel. But that's obvious from the show at this point. Technical brilliance has become a staple, much unlike the show's classic years as a low budget production.
Where the show really shines is in the subtleties of its writing. The ending and the way this episode ties into the arc is pretty brilliant, if heartbreaking. There's also a scene where the Doctor finds what scares him most; and although we don't see it, we know that it's someone whom the Doctor fears. "Of course it's you," he says, as the TARDIS cloister bell rings. This small detail blew the door open for fan speculation, and provide a piece of great writing and camera work in an otherwise average episode.
Not much else to say this week. Next time, the Cybermen make a return as well as an old friend. From the preview, it looks like it'll be a good one. See you then.
