There were a few good episodes, the Santa time travel one, the multiverse one, the mom Corp one. I liked the dune one even though it's got mixed reactions.
That episode 9 was a fucking train wreck, however.
That's a weak defense of the season. The thing that made a lot of the classic episodes classics is that they are more or less timeless. If releasing the episode a year or two later means it's not going to land well, then they should be rethinking the writing.
A great example is the iPhone episode. Its a bad episode because the premise was hardly interesting even when it was relevant, and it hasn't aged well at all.
Original run writers room had a math phd, chemistry phd, and comp sci phd on the team. I think that's why any of the post cancellation seasons fail to capture the wit of the first run.
It felt like they were trying to turn Futurama into an animated sitcom, rehashing other shows. The characters barely had the essence of the previous seasons, and advertising was really shoved down our throats.
