Visuals are its downfall, other than that fantastic. Some things are 3D and some aren't. I think one of the biggest examples of how it doesn't work out is an episode closer to the pilot and is indeed an eyesore all be it a good episode. Was such episode the inspiration for one of the games or vise versa? I can't say for sure.
Kirby always have some dark parts in the game series, and thank the lord that it was passed on here. there are some things that make me laugh to this day since 16 years ago. It's something that I could watch again, but not in the near future at the moment. I give it a B- and that's quite a compliment compared to some other video game based anime/cartoons. Good on ya!
8/10!
