IMO this movie needed to be 3 hours long in order to work right. Reminds me of the whole Justice League situation. I hope one day we get a longer cut just like with that movie.
I guess I can see why Disney would balk at departing too much from the other saga films in terms of length, but I agree with you. And I think at this point fans and movie audiences in general have gotten used to longer runtimes for these big tent pole movies.
An extended edition would be nice; would been a good use of resources after a year without much production.
