I didn't like this episode at all. The cat jokes were lame. The evil kitties' world domination plot was lame. Leela suddenly not having a man was lame. Amy being smart was probably the best part of it, because at least it was different, instead of lame.
Overall, I don't know how I feel about this new season of Futurama. It's not quite as uneven as the first go-round, although, after all, we've only gotten a few episodes so far. There may be more uneven-ness to come. My patience is beginning to wear a little thin, though. One more episode like this and I'll probably start tuning out.
