I only watched a few episodes of the first two seasons but always considered Futurama one of the best cartoons on TV. However I never became one of its followers as I'm not into episodic shows. Some missions of the week were good but others were disappointing. So when I read that season 6 was about to air I thought it would be the perfect occasion to reboot the franchise and provide its long time fans with a fresh and original production.
Rebirth didn't meet my expectations but it should succeed in entertaining the audience. Indeed some situations were quite hilarious. I didn't dig the whole Bender delirium but most of the jokes were funny. However I found some cultural references a bit lazy, at least two films. I couldn't help comparing it to Space Pilot 3000, that I rated 10 out of 10, and they didn't play in the same creative league. Otherwise the characters spirit hasn't aged and I instantly fell in love again with Leela & Fry. I found some scenes touching and even if their relationship is not as super as Lois & Clark I think it has potential and I hope it'll be further developed in the upcoming episodes.
As for the story it wasn't mind blowing but twisted enough so you should definitely be surprised. Visually it's still a miss of traditional 2D animation and 3D cel-shaded CG. However I think they could have upgraded their vision and made it a bit more modern. Some backgrounds were specially tasteless but overall I think the production quality is good. Last but not least it ended with a cliffhanger and even if I don't expect Futurama to switch to a heavy format, with one story for the whole season, it should intrigue you enough to at least watch the next episode, In-A-Gadda-Da-Leela. So it wasn't a two parts pilot but I think Rebirth deserves your attention. But don't expect Futurama to reinvent itself ! It's really like if the show had never been canceled.
