The Ultimate Foe feels like they took the Toymaker plot line that never was (after they nearly cancelled Doctor Who) and gave it to the Valeyard. The Evil Court Room GuyTM all of a sudden becomes this joker figure with circus music and echoing laughter. It's an odd move that doesn't really work.

Also, somehow they managed to fridge Peri and shove her in a random marriage, in that order. Almost impressive, if it didn't wind me up so much
