This show has some of the dullest and dumbest characters I've seen in a LONG time. Pretty much all of them are restricted tight to stereotypes such as the trickster, the snotty rich boy, the candy addict, the hyper tech nerd, I can go on all day. And the villain is pretty darn stupid, even by preschool television standards. I mean, he doesn't seem to have a really good reason why he sticks around in Lazy Town trying to prevent Sportacus from making the town lively again and he gets away with SO many slipups during his missions (Not even Sportacus realizes that it was obviously Robbie doing all the wrong doings until the end, the only person that actually gets suspicious is the Candy Addict which is rather sad.) It's also rather creepy how 85% of the characters are weirdly made puppets and you can't see their legs half of the time and the musical numbers, oh gosh you do not want them playing in the car 24/7, they are just painful to listen to. However, I often get a nostalgic feel every time my sister watches them again, I know it's weird, since I know how much of a trashy show this is but just by watching Stephanie and the puppets experiencing the simple days of being a kid, it reminds me of how fortunate they are to have a live that has no limits, a life where it's just about playing baseball, being a scout, baking cakes and having fun with Sportacus.
There isn't much to be concerned about besides some very mild violence, some pretty bad role models (I'm looking at you Stingy) and they probably should have gotten a "Do Not Try This At Home" sign due to Sportacus's ridiculous stunts. Overall, while I wouldn't recommend this show to anyone over 10, it's one of those shows that it's so bad, it's actually decent.
