The third season of Ben 10: Alien force just played on Cartoon Network today and yesterday, and it was okay. I wrote a really simple and biased overview in the spoiler tag.
-Vilgax is back with the power of ten alien heroes, as opposed to Ben's theme (The only change was Vilgax's fancy weapons)
-Ultimo and co. make a cold open cameo, being beaten up by Vilgax.
-Vilgax has a creepy assistant now, and helps Vilgax absorb the defeated Ultimo's powers
-Vilgax says he's going to beat up Ben in a contest between invader and the invaded, to take over Earth
-Gwen and Kevin are fighting a snake guy, with new outfits: Kevin has a mechanic's shirt that says "Kev" and Gwen has a black vest over a red shirt and a ponytail
-Ben is a jerk
-Ben and Kevin still like Sumo Slammers (Even after that whole warehouse thing)
-Ben shows up to save Kevin and Gwen from the snake-man-thing
-Vilgax's fleet appears
-Max Tennyson is leading a team of Plumbers in training: Manny, Pierce, Helen, Cooper and Alan.
-Max's satellite system detects Vilgax's fleet and he goes to intercept
-Vilgax's creepy assistant sets up a forcefield for Vilgax to teleport into
-Vilgax shows up, Max and team fight him and lose
-Max is allowed to recover and contact Ben
-Ben is being a jerk still
-Kevin has made a large contraption to hack into the Omnitrix
-Azmuth projection pops out of Omnitrix to lecture Ben
-Ben ignores lecture and decides to hack Omnitrix anyway, despite protests from Gwen and Kevin
-Everything blows up
-Ben gets a follow-up lecture from Azmuth, saying he'll never help Ben again
-Kevin is now Metamorpho (Not really) He angsts over being a "monster" again, since his appearance is a mish-mash of the forms he takes when he absorbs stuff (crystal, concrete, metal, rock), and he's stuck like that, even after trying stuff like transforming back or absorbing human skin (ew)
-Ben is missing four aliens from the Omnitrix: Spidermonkey, Chromastone, Goop, and Way Big (Everyone is puzzled about how that last one gets away)
-Ben retrieves all of them except Way Big, using collect mode
-Ben shows up to the duel with Vilgax and promptly gets his butt kicked until Chromastone is crushed, literally. Ben regenerates and takes on the form of Diamondhead and easily beats Vilgax
-Ben doesn't really change that much
-Kevin seems to be stuck in his current form in the next episode preview
