Parasyte

The 17-year-old Izumi Shinichi lives with his mother and father in a quiet neighborhood in Tokyo. One night, worm-like aliens called Parasytes invade Earth, taking over the brains of human hosts by entering through their ears or noses. One Parasyte attempts to crawl into Shinichi's ear while he sleeps, but fails since he is wearing headphones. The creature enters Shinichi's body by burrowing into his arm instead, taking over the boy's right hand. It adopts the name Migi.
Because Shinichi was able to prevent Migi from traveling further up into his brain, both beings retain their separate intellect and personality. As the duo encounter other Parasytes, they capitalize on their strange situation and gradually form a strong bond, working together to survive. This gives them an edge in battling other Parasytes, who frequently attack the pair upon realization that Shinichi's human brain is still intact. Shinichi feels compelled to fight other Parasytes, who devour humans as food, while enlisting Migi's help.

I highly comment the protagonist, Shinichi, for his bravery and sense of duty. He was the only survivor of a parasyte embeddment, making him more unique, wiser, and more punpredictable than the other parasytes. Keeping his own mind and body in tact with a parasyte's coordination, is the perfect tactical advantage in this context. In addition to his physical feats, he is a high schooler and he lives alone since his mother had passed in the hands of a parasyte. He had survived all this time alone (excluding Migi), wandering around wondering of his purpose and objective. At such an early age in such a depressed and shocking situation, he still had it in him to take responsibility of the human race by waging war against the parasyte species.
It is truly an exciting movie to watch. Not only because it doesn't cut bloody scenes but because there was never a dull moment in it! Fast-paced action, mind blowing epiphanies, and unexpected turn of events make the film very dynamic. Among all these, what mesmerized me the most was the awesome detail in the morphing of parasyte to human and human to parasyte. The prostethics and makeup were top notch and the CGI team must've had a lot of skill, patience, and determination to make the visual effects, especially during the fight scenes, such a spectacular sight. 
In spite of this, there were still quite a few things that may have bothered me about the film. First is the random appearance of the parasytes. They can't just show up from nowhere just by falling out of the sky. The film must've shown where they were from and how they got here. Next is the horrible cliffhangers. Though I do realize that this si still the first part of a sequel, the ending could have been a lot better than the decision of the antagonist and protagonist to carry on with eliminating the existence of each other's race. It kind of dropped the climax, and even of its main objective was to pique interest or intrigue its viewers, It felt to me that the momentum of the general flow of the story drop from that point on. I do hope the second part would reveal all the secrets and pick up on the flow/momentum that the first half has left.
