I would've personally swapped Foster's and Samurai Jack. Foster's was fun, but Jack was epic.
I also would've included Flapjack over the Edds, but that's just me.
Megas XLR deservedly earned a place on this list. As long-time Transformers fan, it was only natural that I would also love Megas. I wish they'd bring it back, for Adult Swim, since by the show's content it seems skewed to their demographics anyway and would be a better fit.
That makes three of us then. I never could get into it, and I tried. But I didn't care for the garish animation style, and some of the characters and character voices were too annoying for me to tolerate either. But I don't begrudge others for enjoying it. I'm obviously in the minority on this one, and had no idea that my fellow TZ staffers liked it this much.
