I see no reason to throw out the element that has largely always worked - the cast. What happens when you reboot and it doesn’t work. Reboot again? Eventually WB has to stick with something, why not these people audiences are already attached to? Just put them in good movies.
Well, to be fair, there's just as much a risk a
sequel won't work, as there is a reboot won't work.
A good sequel film isn't guaranteed.
What happens if a sequel doesn't work? Do you just try again because the cast is already in place?
In this case, we don't have an Avengers or The Batman , style critical and BO success of films to point to.
We have MOS, BvS, and JL all of which were received polarizing to negative responses and reactions.
Yeah, we can obviously point to the creative teams, WB leadership etc, but that doesn't erase the fact those films were poorly received from critics, polarized from fans, and met with apathy to negativity from the GA.
At the same time ,the GA at least ,
hasn't been attached to this version of Superman and it's cast.
I mean, there may be alot of people in
fandom attached to the cast , but it's yet to be seen that there's an attachment to the cast from the
GA , which , at the end of the day, is gonna make or break a MOS 2.
That doesn't mean you can't put this cast in a better film of course, but there's no guarantee MOS 2 will be a better film or will generate interest with GA , which so far, hasn't been that attached to Cavill's Superman.
So, there are several reasons why a studio might want to reboot .
But at the end of the day, WBD has made their decision , and all we can hope is that the script is indeed better and that the cast has a good story to work with.
