I found him annoying at first, because he was getting in Bella's way, but now I really like him, as I've realized he was only doing what he thought was right.
I feel bad for him, though. I'm pretty sure SMeyer mentioned in an interview that Billy was a little attracted to Sue and irked (or maybe just depressed as heck) when Charlie and Sue got together. Sue would be great for Jacob and Billy, and Charlie was a fairly good-looking happy-go-lucky guy with two legs, a granddaughter, and a full-time job.
I think it was unfair how some people got perfect endings (that seemed kind of contrived) and others had nothing at all (as though it were purposefully— and as a hasty decision— snatched from them).
