Religious cults really make my skin crawl. In this movie they're hunting people down, stabbing them to death repeatedly like maniacs and act as if they're doing it for the good of the victim. And what's really scary is that you could wake up one day and something like this could go down, maybe not with the demons but more specifically with religion.
As is the case with many low budget movies, the acting is a little up and down. Depending on your level of tolerance for inexperienced actors, this area may or may not hinder your viewing experience. For me personally, it was a non-factor and in some instances made the religious cult side of things feel even more real.
There are some very well executed jump scares and tense moments. The movie doesn't exactly tell us if the world really was coming to an end, or if everyone was trippin' on hallucinogen-laced muffins, or if it's all a dream etc. Sometimes it's annoying when a film doesn't explain itself but somehow End Of The Line manages to get away with it and makes for an interesting discussion piece that really has no definitive answer. They do provide some hints throughout to sway your opinion, such as the opening scenes on the subway and in the shower. And the reason why I mention this is because most people who watch the movie would not have thought to ever go back and look closer at these scenes.
The movie is capped off beautifully with one of the creepiest tunes I've ever heard play throughout an ending credits sequence. It's actually quite a cleverly structured movie. This is low-budget horror done the right way.
