I liked this episode overall, and it was very risky to make a sequel to Midnight without ruining the original episode. They pulled it off well (no pun intended), unlike with Sutekh, and managed not to detract too much from the mystery, while still adding some lore, and it barely even felt like a sequel (which could be a good thing or a bad thing).

The way the entity threw around the soldiers like a tumble dryer did feel a bit cheesy, and I would have liked less casual, early, stupid-looking deaths, and more interesting deaths near the end. There also didn't seem to be much threat or horror (But respect to the characters, they were probably in terror).

Because the entity has evolved, we unfortunately don't get to see any scenes with it talking through people. It would have been interesting to see what would happen if it spoke through Aliss (although it may have taken away from the mystery), and especially if it signed, or talked perfectly, it could have actually been more scary.

TL;DR: They managed not to ruin Midnight, but it wasn't scary enough. (or maybe I'm just not sensitive to horror)
