There's a third option: give the franchise back to Rami and let him make IV.
Ummmmm. No.
Why not? He made 3 very good and profitable Spider-Man films. Even 3 (the least well regarded) still grossed more than $70 million more than the reboot. (US only)
The third one may have made money but so did "Batman and Robin." That's not enough to satisfy fans who pretty strongly disliked "Spider-Man 3" for numerous reasons.
