One thing the Futurama producers never quite got is that Kif is really not funny without Zap Brannigan, and Zap Brannigan is only mildly funny without Kif. It’s the pairing that works. In In-A-Gadda-Da-Leela there’s no pairing, except Leela and Zap. Which might have been funny. Which is sorta funny. But not all that much. In-A-Gadda-Da-Leela isn’t bad, except for the part where it’s like a lot of other Futurama episodes. The retro Zap clips were funny. But most of the garden wasn’t. The death sphere ref to VGer is more of a geek in-joke than actually funny. And any plot that revolves around a V Chip ref is hopelessly outdated, like a lot of Futurama material. In-A-Gadda-Da-Leela isn’t bad. It’s a lot better than sitting through a modern day Simpsons or Family Guy, but it’s not really anywhere as good as it should be. Zap is mostly wasted in episode should have had a lot more professor. And for an episode about censorship that’s being aired on CC, In-A-Gadda-Da-Leela doesn’t exactly push the limits. Instead it’s exactly the episode we would have gotten on FOX.
