The Powerpuff Girls: Dance Pantsed is a special bringing back the iconic superheroines before CN thought of the 2016 reboot that is infamous for being so bad, and yet, this one is bad as well.
In this special, after stopping the evil Mojo Jojo after he kidnaps popular people, the girls celebrate by getting a video game, Dance Pants Revolution. Seeing Bubbles enjoy it, Mojo decides to make another game like it, one that turns the girls into robots under the evil monkey's control, and the professor must save them, when it means revisiting his dancing days, which after being rejected by a dance show, would lead to him going to become a scientist.
Yeah, I can see why this special is hated by the majority of the PPG fan base. For this special, they changed the animation style, as instead of the style used in the 1998 cartoon (or even the flash animation from the movie and the final seasons), they decided to go the CGI treatment, and oh boy, it causes a lot of changes, as the girls look less like the ones we knew from 1998 and more like the Powerpuffs from those commercials they used to do (the ones where they changed the girls' look for some cosmetic line), making them look less like the Powerpuff Girls and more like some girls who got the powers and costumes of the girls. Also, the special does not follow continuity of the series it is based on, as it changes the professor's origin to how be became a man of science (which contradicts an episode of the series where he was a kid in Townsville when the girls go back in time to save him from Mojo Jojo, even going as far as to add Steven Hawking, Issaac Newton, and Slim Jim Wellbody, a parody of Slim Goodbody from those old PBS shows). Also, the special features Ringo Starr, which casts him as the voice of a mathematician who Mojo targets for kidnapping for a cause that, which I won't spoil, is a horrible plot for a villain (I mean, come on, this is Mojo Jojo we're talking about, a great genius who gained his criminal intellect at the same time the girls were created, and here, he wastes it on that?)
However, this special does has some pluses, like getting the original voice cast (including the original VAs for Blossom, Bubbles, and Buttercup, which would not be done come 2016's reboot) and it at least keeps the spirit of the 1998 series, however, not even that is enough to cover the flaws of this special.
