I think some of the bad reviews are overreacting. I loved this show as a kid and I recently rewatched it and I still think it's entertaining. This is a Disney tv show that was mainly for kids back in the mid 2000s, so of course the fashion, jokes and themes are going to be different. If ur going to judge it based on that and because ur too old for the show then it's not really fair.
Even though this might not compare to other Disney/nickelodeon shows I actually think this is one of my favs along with wizard of Waverly place. Idk why ppl would complain about their characters when they're 13 years old so it makes sense for them to do that stuff.
