Personally, I think it’s a little odd to both rent out a theater and also be super concerned about the run time.

But yeah, mileage here will vary depending on whether or not you care about setting up other things. Personally, I think they wasted time on two characters in particular. They would have been better utilized as a post credit scene, based on what we got.

That said, I think a ling run time was a given, based on the sheer number of things they had to accomplish.
