I get it, this is certainly nothing visionary but it's not that bad. I too thought it was one of the worst things created when it first aired but it has grown on me. The creators have developed the concept and the characters over time. It has become a perfectly watchable cartoon that has been put to rest before it got dragged out too long.
I agree that the characters are extremely vapid but they all have their own appeal. It's dorky, dumb and poorly executed but it makes me chuckle. It certainly could be worse. This isn't a show for the average person and I won't recommend it but if you keep your expectations low, (give the first season a miss), it might entertain you.
