I think as a story it probably would've felt way more succesful if it was the pilot episode of a prestige streaming series rather than a theatrical film. The ending has that feeling of things having only just gotten started and the concept would be much easier to explore in depth as a series.
Agreed. I watched the movie after seeing Prey and I found it really good. Badass characters (Soldier, mercenary, drug cartel henchman, Yakuza killer!), drop immediately into the action - no need to establish the usual "protagonist dad separated from hot mother of their child(ren), getting together by end of movie when mom's new bf dies".
It would be awesome as a modern-day Netflix series. Plenty of twists to cover in each episode. "This trap is doing xyz. I know that because I placed such traps myself." Shock ending!
Ronald McNoland appears. Shock episode ending!
Noland flashback episode.
Noland betrayal - shock ending!
The doctor is evil - shock ending!
Etc.
