Frankly, I (respectfully) think that the reviewer was too harsh branding it "corny, corny, corny." After all, this IS a show for young kids and tweens, so naturally, of course it will not please many adults. It almost sounded like the reviewer would expect to turn this show on, and expect to be entertained from start to finish like it was meant for adults.
Would I be captivated for this show to turn it on, and just go on an endless watching-marathon of all seasons from how interesting it is? uhh...HECK no! It's a KIDS show for crying out loud!
However, I do sit down with my 12 year-old child and he loves it. It makes him laugh very often, and I enjoy watching it with him. We laugh together, and we make fun of the main characters at how really dumb they could be. It is true their decisions border on "reckless," but the consequences of their utter silliness never catches up with them, because this is NOT suppose to reflect real life, nor to be educational. I would have prefered if they were some kind of nerds, but still, I don't have to worry about my son seeing breasts jiggling, or about him watching inappropriate scenes. If its educational you are looking for, then no, this show is not it.
But how many times do adults go to their shows for "educational" purposes? With that in mind, I give this show 5 stars out of five.
