Compared to Heroes, anything is scary. How old are the people you know, 8?
Okay, that was slightly harsh, but seriously... I think any movie rated 12 or over is gonna be scary next to Heroes, which in my humble opinion has no fright factor or gore in it at all other than Claire's injuries, which aren't remotely frightening because you know she can heal anything. I really can't think of how an 18 rated horror musical can be less frightening than that.
