Glad you enjoyed it. Now, at the risk of coming off a little too pushy in favor of these two films, might I suggest you watch Resolution, and then again The Endless, as a sort of sandwich? That’s the order I watched them in, and I honestly think that seeing The Endless is essential to making Resolution watchable (it’s even lower budget and smaller in scale with a very slow pay off more in the horror genre), but watching Resolution really heightens the experience/depth of watching The Endless, but you need to watch The Endless after Resolution to get it.
So, to sum up, my recommended “best viewed” order is:
- The Endless
- Resolution
- The Endless again
