I'll give a dissenting opinion. I've loved the Comedy Central reboot. The material is quick and snappy in a way that the earlier seasons weren't, packing in rapid-fire jokes. And it still consistently throws in bits of real science and mathematics, like the famous brain-swapping problem and solution. The movies were uneven, but season six hit a new and sustained peak starting with the fourth episode.
I often felt like the earlier seasons got too caught up in their own worldbuilding and forgot the funny. "The Why of Fry" was my personal least favorite, retconning the entire premise of the show and Nibbler's nature, and straining on a single joke of Fry's stupidity for the entire episode. Other low points included the forced Amy-Kif relationship that had little comedy content and less meaning, Leela's retconned family, and any time filled by Zapp Brannigan's one-note attempts at jokes. Futurama can't credibly do gross-out or shock humor in a world where Family Guy cranks it up to eleven every week.
Futurama is best as a joke turbine playing off the future setting, and IMO strains for misguided impact whenever it brings up how Fry's family lost a son. I never bought in to the heartstring-tugging. The characters are too broadly drawn and fantastical to care about, unlike the Simpsons. The Comedy Central seasons seem to have figured this out, realizing that it's too late in the game for any more meaningful character material. Instead, the show has seriously stressed the pacing and density of the comedy, which for me really shines now.
