Sadly let down by poor script and very low budget. The troll seems to live outside human society but in a shed made from machined timber and fitted with windows and mortise locks. The internal walls are even dry lined.
Actors deliver their lines as if reading them for the first time, with no idea of context. Much is made in the opening scenes of compass directions - "Don't go north", "We will head south", yet nobody has a compass and their map reading skills are such that they do not initially notice that they are standing beside a 12th century church that is not on the map.
Not that it matters anyway, since they never venture more than a few metres from their campsite, and are never away from waymarked paths, cultivated fields, tended grass.
A sub-plot involves a cleric who dresses in full ecclesiastical garb to tend an unused church, while other sub-plots involve a husband-to-be who sounds like a caricature, a gay relationship, a pregnant woman who cannot find a man, the bride's mother turning up for the hen party without the bride's knowledge, captives who escape repeatedly from the troll but never go to the town that is visible from the viewpoint where much of the action takes place.
The actor playing the mother appears in another film by the same director. The impression is one of a group of friends working together, making for a happy atmosphere and an enjoyable experience for participants, but scenes are padded out with meaningful pauses, silences, stares and huge overacting.
The potential is there but the product is tiring to watch.
