I'm a diehard Supes fan, and I was honestly kind of excited
by most of the changes I heard about. The origin and Superman/Lex dynamic had become so stale and predictable that it was refreshing to hear such a radically new take on it.
Granted, the suit-in-a-can thing was too much, but most everything else I really liked.
As for Abrams taking another shot at it, I say why not? He's more than capable, and the Superman franchise (much like Trek before it) could definitely use some new life and energy.
