On top of what everyone else has already said, I’d add that (for some reason) when it comes to Kevin Costner, movie-goers have long long memories about his “ego” projects like Waterworld and The Postman.

Costner went through a phase where he felt that he was big enough to direct, star, and write huge epic films because he was the “only one that could do them right”. And that flopped his career…hard.

He went on from there to do a lot of smaller stuff that was really well regarded. But not he comes back with this, basically another ego-project.

Dude is just Neil Breen with a budget, and people are rightfully still skeptical of any so-called epic that is written, directed, and starring him.

In short, Costner’s epic movies have all pretty much been laughably bad with the exception of “Dances with Wolves”. And Pepperidge Farms remembers that kind of thing.
