If you're a Benson/Moorhead fan, its best to watch this film first. I watched the duo's latest film 'The Endless' before this film, but the two interlink (although The Endless is not a sequel). They share the same universe, and the characters from 'The Endless' interact with characters from 'Resolution'. It might sound confusing, but I assure you it is not. I did, however, feel 'The Endless' was a huge improvement on this film, and see it more as a remake with a lot more detail, and a much clearer view of what is actually going on. 'Resolution' is much less detailed but and leaves a lot to your imagination, but be warned, this film also has some very freaky moments!
