You know, I had a whole big rant following Grefter's statement, but I won't get into it. I'll just say that of all the Giant Monster movies I saw, they either:
A. Don't try at Horror, but either suspense or something totally different (I get the feeling the original King Kong was less a horror movie and more an all out spectacle; remember, this movie was made in the 1930s; its why the movie may be one of the best movies of all time, instead just plain decent.)
B. Fail at horror miserably cause Giant Monsters, oddly, don't work very well for a horror format.
"Godzilla: King of the Monsters" was really the only Giant Monster Movie that really got the "Horror" thing down properly, cause it did things that no other movie really attempted. I'm not just saying this cause I'm a Godzilla fan, but...well, if you see Godzilla: King of the Monsters and compare it to just about any other Giant Monster Movie, you'll understand (or alternatively, the Japanese counterpart "Gojira" works too; I specify that cause the movies are different enough to be considered two different movies, though they both illustrate my point.)
And even THAT movie doesn't really scare you, it more just leaves a disturbing feeling.
To say "Cloverfield wasn't suppose to be Kaiju"...I dunno. Shaky camera aside, it pretty much fits all the criteria of Kaiju other than "is Japanese." So I guess that means its merely "Kaiju styled" <_<
