Worm is absolutely not aimed at teens, and it's not milked. If anything I think it could have been longer.

It does absolutely ruin the believability of any other superhero world. Invincible, for example, is ruined for me. That's how good Worm is. It just takes a loooong time to get there fully.

From someone who didn't finish it (ref. my other comment in this thread), the reason I dropped it was that it felt aimed at teenagers BUT not in the way (I presume) you mean: it didn't feel like a immature power fantasy trying to impress teenagers with flashy fights. More that it switched between "managing superhero powers" and "diving into teenage insecurity and typical American teen romance narratives" from time to time - and IMO not in a way that felt well-stitched together.
