Very weak horror

Rating: 2/10 (4 March 2018)

First off, good horror needs likable and believable characters. No one cares what happens to a character who is a shallow cardboard cutout. If characters are annoying, you start hoping they disappear, which defeats the purpose of good horror. The Descent fails here.
I never got lost in the story. The whole time I felt like I was watching a bad movie. I laughed at several parts that were not meant to be funny. The jump scare tactics are totally predictable.
There is a totally unbelievable shift in the main character's behavior from fragile and scared to stereotypical uber-confident hero, with no reason behind it.
The filming is good, the acting good, the sets are great, and the visual effects very convincing. They're all wasted on a terrible script.
