Cybermen = Okay, I guess. I like the new Cybermites, and the redesigned elements looked okay. But overall, they just didn't feel menacing.
Kids = Thumbs down. The daughter was especially annoying
Clara = Meh. She really didn't do much
Emperor = Knew it from the minute we saw who it ended up being
Story = Meh. Could have been good or better, the kids really dragged it down.
Doctor = Brillant. Matt Smith's "dueling Doctors" is the only thing that keep the episode out of the shitter for me.
