On Spider-Man movie casting: Nope, don't care.
On Bob Harras as DC Editor in Chief: Mixed. On one hand, his tenure at Marvel was marked by some notable mistakes (Bringing back Norman Osborn). On the other hand, I'm increasingly of the mind set that some friction is necessary in a brain trust in order to prevent the problems of group think, and that he might act as an increasingly necessary check on the excesses of Didio and Johns.
On the Price Change: Barely care. I don't really buy singles anymore.
Superman Movie stuff: See tomorrow's post.
EDITED TO ADD: Alan David Doane is selling off some comics. Please go take a look here. Thanks
