I love this show and most the characters but the main character, Duncan, ruins this show. The mom, the dad, his two sisters? They make me roll laughing! Great voice acting except Duncan's, it doesn't fit. Duncan is one of the most unlikable main characters I can think of. A very poor portrayal of a teenage boy. He's completely unrelatable.
The most lovable characters of the show are his mom and dad. Hands down. They are hilarious and the only reason I stomached the entire first season.
