Although the film's ultimate payoff feels a little too big, and too insufficiently explained, to justify all of the obfuscation that led up to it,
the script keeps the audience engaged and guessing right up to the end.
The creature designs are pretty cool, the visual effects are completely believable, and the
script may not be the tightest or the most profound but it does carry the whole thing far enough to
keep an
audience entertained and at least sort of
engaged for just over an hour and a half.
