It's ok, very good for kids especially as its simple and direct in its movements.
Shotokan Karate is actually from Shaolin kung fu styles. A japanese spy during the war ended up training in the Shaolin temple, then came back to Japan and basically butchered kung fu and karate into one. They have very different principles though, and you mighty have issues absorbing it as a complete art.
Shotokan is preferable to normal Karate, but kung fu (NOT wushu) is more preferable to that.
