Frost is among those movies that just weren't what they could've been, but while disappointing it seems memorable.
So in the early parts, we're introduced to the lead characters, who were pretty much the only characters that matter. Anyway, the character scenes early on seemed very natural.
So there's people isolated in the middle of nowhere - I don't remember what company they're working for or why their company sent them out there. The leads awake to discover the group has disappeared.
See, that set-up is excellent. Everyone's missing and frankly, with only two people there. I'm assuming here but I suspect in situations like this someone's supposed to remain behind to administer medical treatment if group members returned injured. But sending one person is an impractical search/rescue party, and while they're waiting for help everyone could be dying. Its a perfect example of how horror doesn't necessarily need anything happening onscreen, just empathising with these people is sufficient.
(IIRC, some members here have experience in the military - anyone know what would happen here? The characters aren't military but I assume the protocol would be similar)
But unfortunately it starts getting disappointing here, because like many found footage films, it turns into a film about people yelling out peoples' names, whimpering in the dark (snow here, but still) and running from something unseen.
A couple of people died, but either came back, but weren't zombies and died again, or something moved their bodies. I don't remember that despite the film twice because the generic found footage content it devolved into kinda killed my attention span.
