I want to go on record to say that I support rebooted franchises that have one of two things.
-Enough history for it to make sense. If you're dealing with a property that has decades of stories that can be adapted to the cinematic format, it makes sense to have a reboot down the line once the current series has run it's course. Iron Man will eventually get rebooted after the current series is done. He's got 40 years of material to work with, so there's always something to adapt to screen. They just have to make sure not to rush restarting everything. I'd say let Iron Man lay low for 8-15 years. Then start it up with a different take on a different story in his comic past. The same can be said for other long standing properties such as Star Trek, Star Wars, etc.
-The second thing that I feel should require a reboot is the potential for future stories. Sometimes there can be more stories told with the same protagonist. There was a point in making a Terminator 2, because you could then show John Connor growing up to be the hero he was prophesied to be. You could have more Predator movies, because the creature from that movie was part of a species of aliens that hunted for sport. When there is more stories that could be told, a reboot could make sense to do. When it doesn't make sense is when you take franchises that have run their course, and the main character or characters have little potential. Jason Voorhees' only purpose is killing people. There isn't much you could do besides that, and after having his ass in 11 movies that should have been it. But there is always money to be made, so we got a ****** remake that is getting a highly probable ****** sequel because there are people who will go see it. When that's run it's course, we'll get the re-remake of Friday the 13th in 2022. People will go see that **** too. I know it makes money, but I'm asking for creativity. People will go see Megan Fox taking a dump for 2 hours if you advertise it enough, so why not make the actual movies people see creative and fresh instead of unoriginal ripoffs?
