I grew up watching Bubble Guppies and the show was alright. It taught kids learning curriculums and "believe in yourself" lessons. But the show has it's problems. The Dance Songs had repetitive melodies and the voice casts keeps changing every season except for Molly's singing voice. The show started loosing qualities around the end of Season 3 and totally fell apart in most of Season 4 which is why it was cancelled. But Nickelodeon resurrected with a Season 5 but removed almost everything from the first 4 seasons. Zooli is an alright character but shouldn't really be bumped as the main character. Overall Bubble Guppies was a good show. For Season 6, I wish they return some main elements of the first 4 seasons.
