With admittedly sharp visual and commitment to practical effect, Harbinger Down has heavy resemblance to The Thing. It will also be appreciated more for fans of old school sci-fi mystery, but unfortunately the effects are not effective. Often done in shaky motion or poorly lit sequences, the organism is a concept better hidden than shown in plain sight and the script is clearly not capable of delivering "feat what you cannot see" horror theme.
The crew of Harbinger finds a peculiar object near the Bering Sea. After hefty debate they decide to poke what seems to be Soviet satellite, a poorly made decision. Most of the screenplay is marred with needless arguments. The characters argue almost in every turn, from feeble matter and even down to crucial life preservation decision.
These are not the people one would want to be with in high stake situation. Cue the combative professor, finicky brunette protagonist and loud ship crews, then you'll have a story too similar to 2011 The Thing. Just like the creature it grows even more muddled the more it progresses.
Visual keeps a good direction for first half. It's clear, very vibrant and camera angle fits the claustrophobic location. However, it mindlessly turns into the dreaded shaky cam, even with found footage touch. There are a couple of good scenes in the making, but these lose thrill when exposed too many times, hence the shaky cam. The latter half uses blur cinematography and ends up contradicting its crisp build-up.
Despite the effect used, CGI or practical, the movie has to be engaging. Harbinger Down has a few glimpses of terror, but neither its effect nor story has adequate quality to keep the movie afloat.
