The Elevator

This is a very underrated film which was surprisingly good.

Given that this is a low budget film (the title is a give away. 90%+ of the scenes happen inside the elevator, which can feel monotonous but the director/script/actors did a good job to keep my attention throughout.) You are made to choose which of the two characters is the foe and which is the protagonist. The movie does a good job in changing your pick through out the movie. And then there's a twist in the end (or a couple). The final shot is also an excellent touch. It gives some sort of relief that everything worked out as intended. Though some can miss it as it wasn't as pronounced.
