PARASYTE PART 1
The film adaptation is handled by Takashi Yamazaki who had previously made the science-fiction film Juvenile (2000) before having some success with Returner (2002) and going on to the live-action big-screen remake of the anime tv series Space Battleship Yamato (2010). Yamazaki also made Stand By Me Doraemon (2014), an animated spinoff from the popular anime series, and had a series of hits with the non-genre family films Always Sunset on Chrome Street.
Parasyte Part 1 plays out like a completely mad film. It could almost be The Thing (1982) reconceived as a typical manga/fantasy anime about a teen hero fighting otherworldly demon figures (it is never specified in the film what the creatures are, as was also the case in the manga, although you assume that they are alien in origin). There is a sense of complete outlandishness to the film from the opening moment where a man is invaded by a parasite while lying in bed and then moments later his entire face opens up like the sepal of a flower to devour his wife. Or of Shota Sometani being taken over and finding his hand has developed a life of its own, extending of its own accord, grabbing Ai Hashimotos breast, borrowing the scene from Alien: Resurrection (1997) and throwing a perfect basketball hoop while his back is turned, it sprouting an eye and mouth of its own to hold conversations with him, even his entire wrist extending out to grab a lamppost and swing him around when they have a disagreement over which direction to go.
From there, Parasyte Part 1 becomes increasingly more outlandish. Particular standout is the blood-drenched scene in the Chinese restaurant where Shota Sometani and the chef fight as the parasites transform into wild blade attachments and tentacles to hack each other apart. And the similar scenes in the alleyway with Shota Sometani fighting Mr A. The only thing that lets it down slightly is the reliance on sometimes obvious CGI effects.
