Now, to move onto the actual things I did like about the movie, the fact of the Underworld portal is one. Speaking of the Underworld, it was a nice little touch about the whole teeth and bone eating that they added. The plot device of the character who knew what was going on was a nice touch as well. And finally, the design of the creatures was pretty well done, even for editing.
And so for the number tally, I was originally going to give it a 2/5, but +1 for design and +1 for Underworld theory instead of paranormal anomaly. Thus bringing it to 4/5
