For a long time I refused to watch that series because I hated that Kim Possible art style. I started watching on a whim when I noticed the whole series is free on Crackle. I still don't like the art style, but the story is pretty good. I might even go so far to say that it might be better than the 90's series (
story wise definitely not art wise), but I have to 1.) finish the series (I got like 5 eps left) and 2.) rewatch the 90s series to get a fair assessment.
It seems like the creators knew this series was gonna get cancelled cuz they blew through a lot of material ( Black suit spidey, Venom, Master Planner arc, Sinister Six, and I'm not even done with the series yet.) for 1 season.
