What I can't understand is why some of the people who like the movie feel the need to rationalize and misrepresent the perspective of those who found it underwhelming.
Some people didn't fancy the movie is all. We all have our reasons, but it's kinda worthless to try and discredit people with such shallow reasoning; we all went to the theater and spent our own money and time on this movie
expecting to enjoy it the same as anyone else.
So far it's been -
"You just wanted an action fest"
"You couldn't get your head away from the trailers"
"You don't understand Godzilla; movie X, Y, and Z from the monster's history was like this too"
At the end of the day, all of the above are meaningless, because the movie just didn't sufficiently entertain some of us for reasons that have nothing to do with any of these. Sure, the movie may have played out at least somewhat differently than it was marketed, but I'm sure we've all seen movies that threw us for a loop and ended up being superlative all the same. Shaun of the Dead comes to mind as a movie that played out very differently from the trailers, and it was exceptionally well done. The last thing that was on my mind after watching that movie was "Gee I sure wish this was more like the wacky slapstick I saw in the trailers!" I think that one of the reasons some people are reflecting upon the trailers is precisely because the movie wasn't good enough to make them forget about them.
It's getting a little old that anyone who doesn't like a particular movie has an ulterior motive or an ax to grind, while the people who enjoyed it are normal, functioning human beings.
