All Ben 10 Alien Force Episodes -

Yes. While the original series is pure nostalgia, Alien Force is the The Empire Strikes Back of the franchise. It added emotional weight, serialized storytelling, and the best trio in cartoon history: Ben, Gwen, and a reformed Kevin.

The only criticism? Season 3 rushes the Vilgax arc because the network wanted to launch Ultimate Alien. But even the "weaker" episodes contain crucial lore.
