this movie is amazing , it does a great job at introducing godzilla as and unstoppable force of nature that is responsible for restoring balance to the world. i like the dark and apocalyptic feel of this movie , and this godzilla looks and feels more powerful and gigantic the the 1998 godzilla film , sure in this movie the monsters have a limited screen time but that's actually normal for most godzilla movies and it helps build up hype for the final fight , which is epic by the way, and the characters are bland and uninteresting, but the medium to fast pacing of the film helps it get over that , and as for the special effect , i think that they are really good and well done , and i don't see what many people complain about , sure the're not incredibly amazing , but the're really good ,plus the sound design is also amazing.
overall i think that its an above average monster movie and its worth your time.
