I've grown a little weary of found footage films, but I'm still a sucker for them. The only reason I took a chance on The Dyatlov Pass Incident is because the historical event has fascinated me for years.
I think therefore I was doubly tough to convince of the film's merits.
I'm pleased to say that final result is a reasonably engaging 90 minutes. For starters I find the characters in this genre of film tiresome in the extreme. Too often they are typically American, young, brattish, arrogant, wealthy and thoroughly dislikable from the get go. Not to mention stupid when the going gets tough. Basically they get more objectionable as the movie goes on until you rather hope they meet a sticky end. That didn't happen here. The protagonists were mostly "reasonable" college students with aspiration, a sense of fun and a thirst for adventure and knowledge. And although we didn't get to know and truly care about any of them that deeply, I didn't end up hating them either.
The background to the original event was well told and a new mythos and twists were competently overlaid in a believable (sci-fi/horror) fashion, tying in other paranormal lore neatly, so it scores well there too.
Likewise the ending -- all to often the final disappointment in too many horror movies -- was well realised.
I've got some reservations about the quality of CGI, but ... I'm willing to let that slide. It's not so much bad effects as, to my mind, not quite "right" effects. I don't want to risk spoiling anything by revealing more.
My only minor complaints are that some of the event were dropped in entirely as plot devices to create tension, and a little too much character dialogue was contrived exposition to enlighten the viewer and move the story forward.
In conclusion: Amazon charged me £8 for this film and I'd say it was well worth the ride.
