What did I love about the original Blair Witch Project? The forest setting. The subtle, urban-legend-style storytelling. The primitive artifacts that had no right to be as creepy as they were. The intensely scary scenes that relied on the unknown.
The 2016 sequel shares all of this, except toward the end, where Blair Witch decides to let up on the unknown a bit. If the movie has one weakness, this is it. While The Blair Witch Project gave us almost nothing to go on, Blair Witch gives us quite a bit more than nothing.
