The movie was terrible. As someone who grew up watching Kim possible and who is an animator/illustrator/artist, the movie was a major dissapointment all around.
The casting was terrible especially kim. She has none not the magic and likability of the cartoon version. I'm sure the kids might be better in other roles but they were terrible as characters from the cartoon. Kim and shegos fights are insanely sub par and Kim doesn't do any of her cool flips, fighting style and stunts as she does in the cartoon, instead she's rolling on the ground and over using a grappling hook in the most underwhelming ways
Athena was unnecessary and monique should have been put in the movie instead if they wanted another main secondary character. Dr drakken was a joke and not in a good way.
The only saving Grace is the the actor who played Ron had his voice and catchphrases down. He did those really well but his mannerisms were off and he made terrible faces . And shegos wasn't the worst. Could've been way better but definitely not the worst. Probably the best character in such a bad movie
