The plan is overvalued as it doesn’t take into account audience rejection

Audiences might not like where you are about to take this franchise, it doesn’t matter if you planned it from the beginning, the second you implement it the audience will reject it.

Audiences don’t like Rey or the fact that she is going to restore the Jedi order, no amount of execution is going to save an idea that audiences simply won’t accept.

The fantastic beasts franchise is obviously meticulously planned, but audiences don’t like the shit Rowling is selling from a foundational level.

Planning for palpatine’s return since the beginning isn’t going to make the idea any less shitty

You might be put in a situation where audiences demand something other than you planned and you will have to scrap your story and reboot mid series in order to avoid audience rejection.

Which puts us back to where we came from with the ST(and how episode 9 came out of nowhere)

We don’t need a plan, we need good ideas
