I think this movie wasn’t very popular because it came across as pro-gun, and this was a year into the first Trump administration. If you think of it in the same terms as the Die Hard movies, though, it’s actually pretty good, and it was possibly Bruce Willis’ last good role before he became incapacitated due to old age. This is a reboot of a 1974 Bronson film with this title, and it does a pretty good job of keeping the same theme, but updating it. The always-entertaining Vincent D’Onofrio plays a supporting role.
Looks like it’s available here: https://www.youtube.com/watch?v=BqluXcZ9RyU but you’ve got to enable DRM (which I think forces you to watch ads? I never watch those, personally.)
