I personally thought it was good. Korean movies and tv shows are bit different, but that’s the point. I loved the action and special effects. The humor is just a great part of these type of movies (kung Fu Hustle is an example). The humor does not take away from the movie. In fact, I think it adds to it. Not for everyone, but “true “ sci-fi / special effects fans should at least watch the movie once. Hopefully watching open minded. Looking forward to seeing the sequel now. 😎
