I thought the previews sucked as well, but they didn't do the movie justice. Part of it was because they rushed too quickly to throw the movie together.
And the box office says not that many people like Kong.
That is absurdly untrue, and for the life of me, I can't figure out where you people are getting this. KONG WAS A HUGE HIT AT THE BOX OFFICE. It was in no way, shape, or form a box office flop.
I think the preview was a fine shining example of what the movie was: a really freaking long version of one of the most copied movies of all time.
We get that because it is 100% true. Kong was not a huge hit, indeed it was almost a terrible belly flop. It cost 207 million dollars to make and on its opening weekend only got 50 mil. Somehow or another it managed to hang on to get a domestic gross of 218 mil, which is just barely break even territory (and actually when you consider the sliding scale of diminishing returns for the company it really isn't break even at all). It didn't even really do that great internationally only making about 50% more than domestic. If the movie hadn't cost 207 mil to make the numbers would have been nice, but with that kind of production budget and a 38 million dollar ad budget the movie didn't do well. It didn't flop, but it sure didn't make anybody laugh to the bank either.
It was #55 on the all-time Domestic list making $218 million. It was #35 on the World-wide all-time list making $549 million.
I would say it did pretty well, but not as well as the LOTR trilogy.
