S6 has been good, in my opinion. There have been some great episodes:|
The Duh-Vinci Code - Hi Animatronio!!
The Late Philip J. Fry
The Mutants Are Revolting
The only real stinkers were In-A-Gadda-Da-Leela, which is weird as it's almost unpossible to fuck up a Zap episode... but they managed it. And Attack of the Killer App, which might just be the weakest Futurama episode ever.
The Xmas special doesn't really count for me... it's just a throwaway.
