"Animal" is actually a fairly decent creature feature. Sure, the movie doesn't offer anything new to the genre. In fact, everything here has been seen before in other similar creature features.
But still, the movie was entertaining and thrilling. And when the movie offers nothing new and is essentially fully a movie much similar to every other creature feature, then what makes it stand out? Well, because the movie follows the "how to make a creature feature" to the point. But it is the creature itself that makes the movie so interesting.
The creature in the movie is unique in appearance and the special effects team did manage to pull it off quite nicely. The creature looked like a strange mutation between a rodent and human of sorts. It did look realistic and was adding a great sense of terror to the movie.
While the creature alone would make for a boring movie, then the people on the cast were doing great jobs with their given roles and characters. And it is especially great that no one is safe and out of harms way. The movie does offer that sense of unpredictability, which adds to the suspense of the movie.
The movie is visually great, but also audibly great. The score is nice and very appropriate to the movie. But the sounds that the creature was making proved to be quite interesting, not to mention unnerving.
It would be great to have another movie made with this particular breed of creature. I can recommend "Animal" if you enjoy a good old fashioned styled creature feature horror movie.
