In terms of 4Kids dubbing, here are my thoughts:
Kirby: Right Back at Ya! Okay dub
Most voice acting is very good, some are just obnoxious and cringeworthy.
The music is great at first, but gets extremely repetitive after 20 episodes.
Editing, not bad, some scenes were removed due to time constraints. some episodes like Kirby Takes the Cake have no edits at all! Some edits were just baffling though, in Dedede's Monsterpiece, they literally thought it was a good idea to censor national landmarks, such as the Mona Lisa!!
The show in general, I'm pretty dang mixed towards the anime, even in Japanese it is not very good. Some episodes such as Cartoon Bufoon, The Kirby Quiz, The Kirby Derby, A Princess in Dis-Dress, Scare Tactics, and A Novel Approach are good! Other episodes such as Junk Jam, Something to Sneeze At, Masher 2.0, A Spice Oddysey, Prediction Predicament, Sheepwrecked, and One Crazy Knight are just so stupid!! The sow in my opinion is just a guilty pleasure. The story is stupid, the characters are fun but also one dimensional, it's boring, very annoying at times, many episodes were just pointless, it's a bit repetitive, stale at times, and just overstays its welcome a bit. One of my favorite 4Kids Dub, but still not anything special either.
