I could just never get into the show and thought it was never as good as its pilot. I think a lot of it had to do with Bloo being a total dickbag for most of the show after the pilot, and Mac being a little bland. Most of the other friends were kinda cool but not really enough to carry the show, and neither were the individual episode stories.
It’s strongly comparable to Chalk Zone in that the initial premise tries to sell you on “endless possibilities,” but then they don’t really go far with them most of the time. Most of the friends were just funny colored wonkey shaped people with maybe extra limbs or something, they were only kinda kooky, not generally all that imaginative to me.
It wasn’t a bad show, I just think it didn’t live up to or make full use of its initial premise.
