The Host is a Korean monster horror comedy that follows the travails of one family to get their daughter back from a mutated fish beast. What this movie did right was to detail near-perfectly a sense of place. Like in Shaun of the Dead, there is an otherworldliness to this movie that just works. It's not real, but once you step in, everything fits according to its own bizarre rules. The comedy and the horror worked extremely well sometimes (especially at the climactic moment), but sometimes they interfered and worked against each other. And it was really funny; it felt odd at first to laugh at dramatic moments, but you quickly get used to it. The script was actually really good; it goes further than you think it will many times. It has a refreshing amount of interesting and unexpected twists and turns and actually contains some very emotional moments. The acting I don't really know how to judge because the movie as a whole was just so odd.
There were also a lot of things I didn't like about the movie. The way it's constructed, it feels like so many scenes were superfluous. Not in the sense that the events happening might not have been important, but that the way they were shown tried to increase tension. It would get you excited and then cut before something happened and when it cut back after a while, everybody would be fine. It negates the entire atmosphere of fear. Also, it wasn't nearly as funny as Shaun of the Dead, the action wasn't as good, and the special effects sucked sometimes (especially the fire crap). The movie wasn't funny enough to be a comedy or scary enough to be a horror movie. I really wouldn't recommend this movie unless you know what you're getting into.IMDb link: http://imdb.com/title/tt0468492/
