The first few seasons were honestly really good in my opinion. It had a real actual plausible sitcom view, with a cartoony spin on things. It's a lot easier to relate to any one character for reasons, be it their actions reminding you of a sister, brother, your mom or your dad, and even the kinds of friends you had in elementary school/middle school. You actually begin to root for them, or feel embarrassed for them, award etc. The humor is usually corny, and lands but the issue the shows having now is it's falling into a rut really bad, with their main characters growing a bit stale. Every one of Bobs wins have been halfwins this season, and if he even gets a win, it's never a full one, which makes the ending predictable even more than it'd normally be and it sucks to all end and back to see Bob always the one messed up.
Otherwise a lot of the other characters has had good development, except honestly Tina which makes sense because she's easily one of the most popular characters to obsessive fandoms. Tina and Louise but it's much easier to make developments on Louise's character.
