It's me Pointy have a lot of points in my reviews, hints the name,
This is a typical Disney XD TV show. I truly don't care for it because......
1) No positive role models, you have a dumb older brother (which really is his character it for the comic relief) a smart, but rude middle brother and a girly high school sister. Plus Leo.
2) Unlike my taste and very much like it's normal format, Disney XD has created a comical TV show for preteens and teens. Basically you have four siblings playing pranks, trying to fit in or fighting evil. Yes it does have a back story about sibling love, loyalty etc., that is very slight.
3) Like all Disney XD TV shows, it has some modern language, which doesn't bother me very much, but for some parents can be a big one. Though I would never let my children say some modern words.
So to the positive, this is a amoral TV show. Amoral means in between. It's not bad, but it isn't good. It won't harm your child, but it is mostly a waste of time. So here's my advice to you if you have the time, watch all of the episodes, make a list of the dumb/useless ones, the okay ones and the good ones. Then allow your child to watch the good ones.
