definitely agree with A Quiet Place being on the list. Horror is one of my favorite sub-genres of films, and I really enjoyed this one in particular. I actually went to see it twice, which is very rare for me, and even rarer when it's a horror film.
Another one I enjoyed was Searching. It follows the same, "oh this was all filmed from the perspective of a computer", so going into it I didn't have any expectations of it being good. However, it actually surprised me with how well it was put together. I don't want to spoil it for anyone, but if you haven't seen it I would definitively recommend it.
