While in places Lowlifes teeters on the brink of dismal, there is just enough to keep you watching to the end.
The storey is run-of-the-mill blood and splatter. There is a twist, which leads to an interesting finale. Beyond that, there is no noticeable character development. Which is a shame, as there is a lot of room to expand on some of the characters' motives.
Given the fairly narrow scope of the film, it is not surprising that the cast could do little more than service the script. The dialogue revolves around vignettes designed around shock or humour, rather than narratives that build a story. Because of this, the characters are quite superficial.
If you do make it to the end you might find yourself thinking, as I did, this is a mediocre film that could really use a better written prequel. There's novelty worth exploring, and for that reason I am glad I watched it.
