The only recent Giant monster films, not just monster films, that i can think of that are more on the horror side, are Cloverfield and The Ritual. Even the monster in The Ritual isnt that large but ill still throw it in the giant category. Would anyone else like to see more giant monster movies done in the horror style?
Also, i know there may be some older movies with giant monsters that may have been classified as horror, but im talking more modern day horror films.
