These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Special Effect Failure: The digital demonic faces some of the vampires get when extra bloodthirsty looks pretty silly, ironic since the traditional make up effects are quite terrifying. Also, at one point you can see wrinkles in the costume the actor playing the Shape wears.
Visual Effects of Awesome: The icicle and snowball, the practical vampire make up, the vampire eyes(well, most of them) and tracking shot in the cabin in the beginning of the film are very impressive considering the film's budget was 3 million dollars, in other words half the budget of The Room.
What an Idiot: The medical intern Sebastian takes the prize, as he is responsible for most of the deaths in the film after a horrible decision.
