I enjoyed the movie. It left me wanting more. Will there be a sequel? It was a little reminiscent of other stuff Bob Odenkirk (Saul of "Better Call Saul") has been in. I'd bet there's cross-pollinating of writers/staff with "Saul" and "Breaking Bad".
Major spoiler: the entire bus fight scene is on Youtube. What you don't see in the Youtube clip is the main character praying out loud for the bus door to be opened so the bad guys can come in. It's momentarily confusing. After the fight progresses, you start to get the idea he likes this kinda' thing.
