What starts out as a promising exploration of a twisted father-son relationship gradually morphs into a Thing-esque body-horror romp without much in the way of substance. I was all in for seeing how Abraham adjusted to his "real" family, with the menace of his false father Noah hovering in the background. Was definitely less down for the man vs nature (If that's what they want to call it) siege that dominated the last third of the story.
On the art side, the quality vacillates wildly. While it kinda adds to the fever-dream-ish vibes of the overall story, at times it made some of the panels busy and confusing. Lee does have a knack for ghoulish close-ups of peoples' faces though, I'll give him that. At his best his work in Mountainhead reminded me of Sam Kieth's work on the Maxx.
Lees on the other hand definitely fumbled the writing of this one for me. I wasn't the biggest fan of his prior works (Sink, And Then Emily Was Gone) but they had a certain chutzpah and gristly flair that made them compulsively readable. They also both took place in the writer's native Scotland, giving them a rough-edged authenticity. The Glaswegian comics scribe struck me as a bit out of his element in his writing and characterizations of a Canadian mountain community. At first I relished the idea, as a Canadian myself, of seeing a quiet, WASP-y Canadian town have all its rot stirred up a la Stephen King. Alas, the setting felt reduced to window-dressing. There's even some awkward dialogue moments between the kid-protagonists where it just feels clear that the writer isn't North American, nor a kid himself.
Issues like that, coupled with a lack of solid arc for Abraham, keeps Mountainhead from being an idiosyncratic, cult horror like past Lees works. What we're left with is the trade paperback equivalent of a Netflix original horror film. Entertaining at times, no doubt about that. I just wish I had cared more about Abraham and the inhabitants of Braeriach than the writing allowed me to.
