Actually, I'm really hating the cracks in time plot. One of my biggest problems with the Doctor Who reboot is that idiotic plot device. They take something about the final episode of the season, and sprinkle it through every episode before it. It was fine when they did it once. Now they're working on the fifth time. The mechanic is old and boring, guys, find a new one.

Season 1: Bad Wolf
Season 2: Torchwood
Season 3: Vote Saxon
Season 4: Images of Rose, and the Doctor/Donna
Season 5: Cracks in Time

Really? Really?! How many more times are you going to do this?
