Hate to Say It, but...
The show was pretty much crap. The sketches weren't funny, the music mediocre, and the cast, most of them were so green! Now, I looooooooooved MMC back in the day. I remember crying one time, when I missed one episode (pathetic, I know!) -- JC, Justin & Ryan were my favorites - by the way, What happened to JC?! He's hideous now! I came upon some of my old tapes the other day, and popped one in just for old time's sake. It was horrible. Sure, kind of kid-cutesy, but pretty embarrassing.
I admit I do still have a fondness for the show (based on my childhood memories, clearly), but for those people who are looking for episodes to buy, I don't think it's worth going out of your way for. You might be disappointed and possibly disturbed.
