The film is really good and well made, making good use of different camera angles. Regular filming from above giving a really interesting shot angle. The make up and facial changes and blood, special effects were very well done, adding on fake teeth and eyes. Make for a lot more realistic characters.
I found the first 1&2 quite good, but then it just started getting ridiculous. However if they make another after The Marked Ones that actually carries the original story on, I will have to watch it just to see how it ends.
