I have watched the first 6 episodes and so far I would give it an overall grade of B-. I do not like the new Gypsy at all. I'm sure it might be seen as kind of sexist now that the only "feminine" character in the original cast (until Pearl Forrester showed up) was kind of dim, but I liked having one character on the show who was sort of sweet and not full of snark. (Plus, Gypsy was the greatest thing to happen for Richard Basehart since Voyage To The Bottom Of The Sea went off the air.). The new Gypsy, although still not seen all that much, is just another smart-alecky robot.
I am undecided about the new "test subject", "Jonah Heston". He hasn't made much of an impression on me one way or the other yet. I do like Patton Oswalt as "TV's son of TV's Frank" and wish he were used a little more. There was a funny cameo by Jerry Seinfeld in one episode.
The quality of the jokes has been uneven. A few of the lines have definitely been LOL funny and they have made some references to classic lines from the old series ("Watch out for snakes!", "SLEEEEP!" and even a reference to Rowsdower). They do seem to be relying on more fart jokes than I recall being used in the original shows. Maybe the movies they are using now are more "dialog heavy", but it also seems that the jokes are not as fast and frequent because they don't want to talk over the dialog of the movie. The skits in-between segments of the movies have not been all that great.
If nothing else, I did finally get to see Avalanche, a 1970's disaster movie starring Rock Hudson and Mia Farrow (with all the blazing onscreen passion you might well imagine from that pairing) that I never got around to seeing before.
