I only watched this first episode so far but I am pretty sure I will like the rest of it as well. I am very comfortable with the short span of time given to the story. In fact you can guess easily where it is going so there is really no need to drag things out. I think this show is not a very serious mystery horror show. It has a very simple promise, which is to present the audience an urban legend, twilight zone sort of idea to enjoy and maybe think further before you go to sleep. What would i do kind of questions came to my mind. It does not ask you to suspend belief or commit so seriously into anything happening on the screen. For this episode at least, the fast unfolding of the events in this story actually provided some comic relief and softened the heavy dramatic aspects. Just sit back, watch it and toy with the idea yourself. It is a folk tale after all, need not be realistic!
And one more very important thing : USE THE SUBTITLES ! the episode did not work with dubbing . It was unwatchable. Really decreases the quality of the acting . Definitely should be watched with original Norwegian conversation. That is usually the case with all Nordic cinematographic pieces anyway (unless the Nordic actors themselves speak English for international audiences) but here the english version's quality is so low that the whole atmosphere is lost.
