Yes.. is true, there's already a review of the second Futurama movie, the Beast with a Billion Backs. Thanks to Steve for letting me know that the people of Screen Jabber already has the movie, and some of the higlights are:

[WARNING: SPOILERS]

Kif has asked her (Amy) to be his Fonfon Ru, which I guess is kinda like a wife. Or something. After a quick side trip to Kif's homeworld of Amphibios 9 for the ceremony.

Farnsworth and his mortal enemy, Professor Wornstrom, vie for the right to send a mission to explore the thing (the space rupture).

[...] We get loads of callbacks to episodes of the show's first four seasons — the Harlem Globetrotters pop up, as do those horny Amazon women and Pazuzu [...] Robot Satan is back

The big question: is it funny? Yes indeed. Is it funnier than the first one? Again, yes indeed. All those who complained that Bender's Big Score lacked laughs will be eating their words this time round.

So, it seems that the second movie will be better than the first one, and I loved the first one... There's also a little more info about the third movie, Bender's Game. For more information please visit the Screen Jabber article, and don't forget to preorder the Beast with a Million Backs! while you can.
