It's me Pointy, that's my pen name. Here's my point review:
1) Why, if you should, let your kids watch this? Answer: It is a dumb TV show, but it is a good one. I made a list (which you could do if you're that skeptical) of which episodes were the dumbest and which weren't. It's one of those shows you let your child watch only every once in a while. And the reason why they should watch it. It test character and friendship. But kind of in a cheesy way. (I know my review sounds very unorganized.)
2) What language does it have? Nothing bad since it's for preteens. Mostly modern words like: Butt, jerk, freak, sexy and poser. I would never let my child use these words, but they are so spread out and faintly said that a preteen wouldn't notice them. let alone a ten-year-old.
3) What sexy stuff? Well the original review talks only about the first season, I have watched all three seasons. (Oh and a fourth is coming out). They sexy stuff is mild teen crushes and dating. I personally don't think you should date at age fifteen or sixteen, but that's only my preference. There are four kisses in the whole series. Kim kisses Milton accidentally, Kim kisses Milton to release a spirit, Jack and Kim almost kiss, and Jack and Kim are told to kiss for a movie, but end up not doing it. Jack and Kim start dating. All of these are mild, though with a critical eye as a parent I don't like the fact that there is any of this.
4) What violence does it have? Well none really, I just put that one up so parents would know this: Martial arts are used, but in a slap stick way. No body bleeds and no gore is in this. The characters always recover quickly.
Now that I've told you all the negative things about Kickin' it, here's the good parts. Jack through the whole series is a great role model, all of them are, but mainly Jack and Kim. Anyways through the series his character is kind of downed, meaning he slowly is turning into a more funny character rather than a role model. Another good thing is each episode has a theme, usually one to two stories (it's usually two to three stories intertwined) tell about good friendship, loyalty, forgiving, peer pressure, set your goals high, seeing the real person, etc. though each episode has at least one story that is for comic relief, and even though a lot of the slap stick comic is dumb you still need to laugh people, so don't say the comedy it bad. Anyways. this is a good series, my favorite characters are Jack and Kim, I do not condone dating at a young age, but the two of them were made for each other and I like the fact that they talk about equality in one episode. So for smart parents who have the time. Watch the episodes and make a list of which are good, which are dumb and which are okay. I will promise you, the dumb section will be fuller than the good section, it's just the way it is. Oh and Disney channel, yes they are going down in morally good shows, but Kickin' it is pretty good.
