>n order to complete 65 episodes for the 1st season, Warner Bros. and Amblin Entertainment contracted several different animation houses. These animation studios included Tokyo Movie Shinsha (now known as TMS Entertainment), Wang Film Productions, AKOM, Freelance Animators New Zealand, Encore Cartoons, StarToons, and Kennedy Cartoons. Tokyo Movie Shinsha also animated the series' opening sequence. Warner Bros. staff disliked working with Kennedy Cartoons due to the studio's inconsistent quality, and episodes that they animated were often subject to multiple re-takes. In other cases, such as the debut episode "The Looney Beginning", portions of Kennedy-animated episodes were re-animated by another studio.

I can't find a larger version of this comparison image but you can see why they didn't like dealing with Kennedy Cartoons.

IIRC Kennedy was just a husband-and-wife team working out of their house.
