I don't really care who owns the rights, but I really don't want to see a reboot again so soon.
Or I guess more accurately, I don't want to see Garfield and Stone recast and another origin story told, because as much as I really liked Raimi's Spider-Man movies, I liked this last one even better. If Marvel got ahold of the property and tied it in loosely with their ongoing universe I'd be fine with that so long as it doesn't interfere with what Webb's planning for the second movie.
I really don't think future ownership will interfere with the next movie. IMHO, it will be claimed by the current Sony owners as "in the pipeline" and they will have full rights to it.
Movie 3, will likely be under discussion, but, I think II will proceed basically unimpeded
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
