The first episode, Rebirth, had a lot of elements that Futurama episodes of yore contained that made me love it: social commentary, extrapolation of current technology into future technology, apparent deaths, sci-fi twists and a bit of character development. The trivial elements are certainly present like Fry's homeresque stupidity and cheap jokes but that's not something that distinguishes Futurama from other comedies. I think that the professor's quirky inventions and old age behavior remain strong in this series and for some reason never loses its humor with me. The professor can (and often does) invent anything that is necessary for the plot as well as sending the crew anywhere in the universe to deliver a package. Rebirth has a lot of those classic elements when the professor plays god with bringing the crew back to life as well as going to the cyclophage habitat planet to sacrifice Leela. If this sort of predictable formula annoys your or bores you, Futurama probably got old a while ago but for me the high quality of animation, music and voice acting really make willing to belly up for every contrived new world that is conjured. Rebirth also addresses Fry and Leela's loneliness and isolation but has a cheap cop out (the ones in love turn out to be robots) at the end to avoid any permanent character development at the end.
Episode Two, In-a-Gadda-Da-Leela, was less satisfactory for me because it dealt with an old card: Leela engaging in coitus with the Zapper (and his insecurities). While some parts made me smile, it just wasn't as funny or memorable as the older episodes. Some parts had their moments (Obi Wan Kenobi GPS with a different voice saying the wild cards was a favorite) but the overall story and plot didn't really pass muster for me. I enjoyed the cheesy black and white "The Transcredible Exploits of Zap Brannigan" (reminded me of many MST3K episodes) and of course you have to love Zap heavy episodes with his ill formed sentences and logic. But aside from that, we get a cookie cutter invention from the professor and nothing too impressive with the explanation and resolution of the V-Giny death sphere. I think a lot more could have been done with that.
All in all, not bad. I was hoping for more secondary characters that I've loved from the first four episodes like Roberto or Scruffy. These secondary recurring characters have always been a favorite of mine and a strength of the show. I guess I can't expect them to put one in every episode but I was disappointed there weren't a whole lot from the movies and none from these two episodes. Definitely worth my time to watch and for those of you outside the United States, you can find torrents out there online by searching for Futurama S06E01 and S06E02. I hope they make it all the way through this sixth season and I also hope Comedy Central ponies up for a lot more after that. If there's one show with usable potential, it's Futurama and its endless possibilities. I mean with the amount of money being dumped on other crappy shows, you'd think a fraction of that could be afforded for a show with a highly devoted following. Then again Firefly is long gone.
