Thank god i found this site! Its a horror movie that deals with the armageddon, but it’s pretty recent. They go underground and into these caves a lot, slightly reminded me of “as above so below”. It took place in an eastern country, and I think there were two main girls that were vacationing there. They stayed in a very pretty hotel and they showcased a lot of eastern aspects of the city. There were these scenes taking place in a church and someone being tortured there. There were these demon things that would slowly take over the people if they came into contact with them, I think everyone died in the end too. The military was there too, they prevented everyone from leaving the city(because all of the demons were out and about) while the main characters went underground in the caves to escape the city. pretty sure they died before they got out tho. it was in english and i watched it online. (in color, too)
