Lacked impact, but ended well

The ending and big reveal near the end are pretty good, but the movie really has trouble getting there. It was a bit unlikely, flat and lifeless, and failed to harvest the creepiness of monasteries and it's rituals. She didn't even react to those nuns lying on the floor, for crying out loud!

A torture movie for research rather than enjoyment

I actually got used to the torture scenes of amputations and various acts with sharp objects. I actually became somewhat interested in, and empathized with, the mysterious killer. But mostly I still felt sick and depressed rather than amused after watching this.

Wish I felt it more, but adept

I am not sure how realistic this was, and found the sergeant a little too wacky to be credible. But overall the story kept my attention and did a reasonable at depicting the dilemma of loyalty versus morals - although I do think they could have hit harder.

Only the monster is unique

Trolls are nice monsters for a change, and I somehow expected this to have a Nordic class of restraint, mysticism and folklore. Instead, they went with a full-on Hollywood blockbuster monster-movie vibe, with all the tired cliches and annoyances that come with it. Like you've already seen it.

Improves with age

Upon first viewing I was annoyed by unnecessary vague way everyone talks and the focus on their petty problems instead of the maze itself. And while these problems are real, upon second viewing the core adventure - with some mystery, action and horror - became more evident and enjoyable.
