I like the practical effects even though sometimes, they're a little too stiff and not as good as they could be. Plus, you never get a great look at the monsters like you want. The little bit of CGI is done well too aside from the blood glacier itself, which doesn't look so realistic. The major issue with this film is the horribly-stupid, hilariously-bad ending. What were they thinking? It's so bizarre and silly. I won't spoil it for you, but I think for 99% of the people out there, it's going to ruin the movie, which really was pretty good until they decided to jump off a cliff with that bonkers finale. I get that they kind of set it up, but it still doesn't make any sense, and it isn't believable at all. I was insanely excited for this one too, and I was into it until the filmmakers decided to metaphorically put a gun to their head. It really has to be one of the worst endings ever. It sucks too, because what I'd love to see more of are monster movies with good, old-fashioned F/X. Oh well, I hope Harbinger Down is good.
