Looks great..story and acting not so much Visually amazing but it's not a very good movie. The story is very weak, acting was mediocre with very bad dialogues. A couple of decades ago I'd totally love this movie especially with all the Japanese influences. There's action, a bit gruesome at times but thankfully these aliens don't bleed red. I was planning not to have several anime, 80/90ties cartoons or Japanese monster movies flashbacks while watching this but that ended up being difficult to ignore.
Guillermo del Toro has a beautiful creative mind but I don't see how this movie has a director. The movie has so much cgi in it, it's completely made by the story-boarders, editors and cgi tech guys. I can see someone being an art director guiding movies of this sort but the concept of directing a movie is totally lost in movies like this. And since it's not such a great movie I can't even say it's well directed.
Online cgi artists complain that some of the stories tend to be weak giving them a bad name but I don't see how the people who are suppose to write good stories get paid enough since all the money is needed for the cgi!
But anyway if you are looking for an sci-fi monster action flick and are not much concerned about the quality of the storyline. Then watch it! I like the Japanese influences, the visual works, sci-fi in general so it's hard for me not to watch any type of sci-fi movie (especially the dystopia type) LOL. But the story is really weak and some of the acting made my toes curl.
