After the soul-crushing darkness that was Dead Money I found Old World Blues to be the most fun I've had in a while.
I definitely get a Mystery Science Theater 3000 or Futurama feel from this one. Since I grew up watching reruns of cheesy 50's sci-fi movies (I'm old) this was right up my alley.
(Spoilers)
Between the Toaster and Dr. Dala I laughed most of the way through this one. Except when I was getting my ass handed to me by robotic scorpions and lobotomites.
Trying to convince my brain to come back was laugh-out-loud hilarious.
