So I ran across another list from WhatCulture and I have to give it a thumbs up because they really have noted a few good diamonds in the rough that I too highly recommend.
First off - The Void. This movie exceeded my expectations by far. To be transparent about this, I am a big Lovecraft fan, down to the original fiction, to inspired art and various means of gaming (Arkham Horror, Arkham Horror LCG, Mansions of Madness, Call of Cthulhu (video game)...I'm not an RPG person, but there's a plethora of content there. Anyhow - The Void. This was simply bizarre, disgusting and intriguing all at once. On a macro level, I'd say it kind of reminded me of not-so-family-friendly Stranger Things with a little sprinkle of cross-dimensional cultism. The effects were fantastic and it carries a high production value for a small release movie.
Also on here - Starry Eyes. This movie blew me away and firmed my belief that Alex Essoe very well could become a household name soon enough. I was not at all surprised that she was cast to play the iconic Wendy Torrance in Doctor Sleep, although disappointingly it was a minimal flashback role (in the theatrical release at least). Starry Eyes let's you feel the dirty grit of Hollywood and the desperation it can bring upon someone to make it in the film industry. Of course, this is not an original idea but Starry Eyes puts a firm horror spin on that plot line. While it is a "How far will you go to make it?" story, it's very stylized and brings about a fairly grotesque and unique ending. I loved it.
Also on the list - The Invitation, The Autopsy of Jane Doe and Train To Busan.
