If you loved Ava, try Copshop
A bridge between a film you've already seen and one most people haven't. Copshop has roughly 3.0× fewer votes than Ava — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theysit in Action / Crime / Thriller territory. If that's the register that drew you to Ava, the second film will land in a comparable space — through a different lens.
What Copshop is
Gunshots, Nevada night. A determined conman books a cell to evade a hitman's bullet. Both men land in the same station, and a rookie cop referees. Carnahan's hyperkinetic action style grafts well onto classic siege thrillers.
