It's okay.
Chadwick Boseman has never struck me as a particularly strong actor, but he sure is earnest so I give him points for that.
The film has some really dynamite scenes, but on the whole it's entirely too predictable and familiar. I was awaiting a twistier ending, but nope, super procedural all the way through.
And at 01:39:00, it's pretty dang short. I want mo for my money!
