Re: Wanted!
I read 'Wanted' recently as well, and I liked it, then got to the last to pages and loved it. But then my favorite scene in any Hitchcock movie was the part in 'Rear Window' when Jimmy Stewart's girlfriend says "look at us, we're all heartbroken because nobody was killed," so YMMV.
Anyway, my take on The Killer's powers were that not only was he supernaturally accurate, but that he could Suppress or Dispel his target's defenses. Except for Sh*thead, who obviously had some Power Defense paid for by his Susceptibility to household cleaners. If you ever read Stormwatch, there is a character named Rose Tatoo who is the spirit of murder - The Killer is her, but with a Y chromosome. And dialogue.
