But seriously? A third reboot? I think people would really be fed up with that. The only hope is for a good sequel.
Well Spiderman is getting a third reboot, and fans are actually excited about this as it will be the first time Marvel will get to work on their own franchise, and unlike the Fantastic 4 Reboots, each of the reboots have more than one movie attached to it, and were not universally panned as all the F4 Movies have been. (with the exception of Spiderman 3, that movie was just wierd.)
Fans want to see the F4 movie made by or in collaboration with the Marvel Studio's that would renew interest in the franchise.
