Same thing throughout whole movie

Rating: 5/10 (25 December 2019)

I am not a fan of this movie.
The thing that made me off is the same thing through the whole movie. Survival in a sadistic veteran's home. Through the whole movie, you can see only one development in plot and it is really not a big deal and ending is just meh. You can not create empathy with the veteran due to his acts. After watching the movie, you put yourself in writer's position and begin to think how to make a better movie by using this good content?
Yes the content, the theme is really good but the processing of these elements are just mediocre. 5/10
