I have to disagree (maybe it's because of my age), but I watched 3 episodes of 'Scarred' in a row on Saturday night, my 14 yr old brother turned to it when there apparently was nothing else better on TV, and I really liked it.
I guess I liked it not because of the 'seriously hurt yourself, become famous' idea, but rather because it shows just how dangerous those extreme sports can be. If anything else, it makes me glad I've never attempted to do any of that stuff on a BMX bike (yes, I have one) or rollerblades. I have horrible balance, so I've never been able to skateboard. Just about the only sport I'm good at is skiing, and even then, I'm not inclined to show off and do jumps, etc.
When I was a lot younger, like 10 years younger, I'm sure I wouldn't have been afraid to do tricks and stuff, in fact, I was really good at rollerblading, I could go backwards and stuff; I even fancied myself a speed skater at the Olympics, hehe.
Now I have this thing called FEAR. It won't let me do anything remotely dangerous for fear that I'll break something. In 23 years of living, I've never broken a single bone in my body, and I'd like to keep it that way.
The reason I like 'Scarred' is because I feel it shows the dangerous side of the sports, the side you don't see in the skate videos on DVD and online. For every one successfully-executed extreme-sport video, there's probably at least 5 that have ended up in serious injury to the participant(s). Kids need to see that. Parents need to see that. I'm just glad my brother and his friends grew out of their skateboarding phase; it was fun while it lasted, and I admit to vicariously living thru them, but it's a relief that they've moved on to more safe things, such as texting and video games
