Max Steel was just a cheap marketing attempt to cash in on the extreme sports/secret agent shtick in order to make an action show guaranteed to appeal to 10-year-old boys. Boys like secret agents, and they like extreme sports, so what if someone made a show about an extreme sports athlete who's also a secret agent? Thankfully, someone did.
The only thing I've witnessed in recent years which was more wannabe-cool than Max Steel was that Kids' WB TV movie Zolar, about a skateboarding alien. In one scene, it was revealed that all of the world's extreme sports athletes were actually space aliens. The director should have been lynched for that one scene alone.
