This opinion is unpopular, hence the fact I call this episode overated. There is no dip in quality in this episode, everything from animation to voice acting is just as good as the episodes that preceeded and succeeded it. However I cannot get over the fact that Bart is punish for exposing Lisa's lies. I won't go on a rant about it here. I'll just bring up the simple fact that Lisa lies to her new friends and the moral of the story ends up being something along the lines of even if you get exposed as a liar your friends will still like and want to associate with you!
