It mostly looks nice, although there are tilted camera shots that have no reason and a bizarre bit where it went to black and white for no purpose (I thought for a moment it was to represent monster-vision, but it was not POV).
The actors are unconvincing, the period detail is shoddy (1813 and there are semiautomatic rifles) and the pace is slow...
The writing is bad. Our protagonists get ideas from thin air (The monsters attack their cottage and then leave, depositing the corpse of a woman on the porch - therefore, they want us to bring them women... to mate with).
The same protagonists behave badly (kidnapping a local woman to use as bait... twice) and stupidly (in the forest at night, hunting nocturnal monsters, they fail to cover each others back. This sort of thing is constantly happening.
There are monsters. The pre-credit sequence, not unlike John Carpenter's The Thing shows us they come from outer space. But don't expect top see much of them and don't expect them to be remotely interesting.
Oh, and women in this movie exist solely to facilitate alien reproduction or to motivate the pathetic male characters'
