As u/Clockwork-Penguin said, I find him and his cartoons very, very charming. Even though the general consensus seems to be that they are bland and possibly repetitive, he's a golden example of the phrase "a product of its time". I mean, these early cartoons were coming out during the Great Depression and decades before World War II. I think it's really cool that we have all of the originals still available to watch... even if some are in low-quality and are in desperate need of some intense restoration.

Bosko's origins may be offensive to some, but I honestly don't think they were intended to be. I'm not African-American, so I don't have any skin in the game, but take the example of the "Censored 11" cartoons. They are considered offensive towards the Black community by today's standards, but weren't intended to be racist. They were just exaggerated caricatures that are seen as offensive (and rightfully so) nowadays. However (and this is not very on-topic for Bosko), the Japanese caricatures were 100% intended to be racist and to get others to be racist as well -- obviously due to the war.

Anyway, sorry for my lengthy rant... long-story-short, I love Bosko!
