Larry Fessenden has proven to be a very good director of very low budget horror films. He makes monster films where the monster is an afterthought, if there is a monster at all to begin with. His knack for atmosphere, creepiness, tension and claustrophobia is almost unparalleled but it is his quirks and idyosincratic flourishes that really make his films shine.
Consider the next to final scene, when the reality of what has been happening is revealed. A lot of it is filmed from 1st person POV which then cuts to a similar shot that took place decades ago and has no relation whatsoever to what is currently happening and everything to do with who it is currently happening to. The transition is not jarring, but natural and oddly affecting. The combination of music, tone and the artistry behind the combination of shots makes it work beautifully. A lesser filmmaker's attempt might have resulted in "pretension" (that most odious of words) but Fessenden, whose films are composed of precisely such moments, posesses a deep understanding of the language of film. He is proudly a genre filmmaker but one who does not limit himself by genre trappings, but by his own imagination (and, admitedly, budget).
"The Last Winter" is not a very good film, certainly nowhere near as good as his "Wendigo". Its screenplay is a complete mess, the editing during the first third is all over the place and the characters contradict eachother and even themselves. Yet...the film is so atmospheric, desolate and peppered with small moments of beauty that it is almost worth watching. Even within its confused and confusing screenplay there are scenes that are so clearly allegorical (a particular exchange between two characters is clearly meant to represent the two opposing views by scientists and fundies on climate change in US culture, their arguments and their reality, for example) that with more consistent writing we could have wound up with something special. What we have is what we have, however, and while it is not exactly good it is certainly further confirmation that Fessenden is the real deal.
