If memory serves STID (for me anyway) did worse because they spent more to make it and market it and as a result made less relative to how much extra they spent. On top of that it also had really tough competition the week before and the week after its release.
I fully expected it wasn't going to live up to its new budget.
And I'm not the least bit worried in Trek's future. As long as people keep going in droves and the movies are getting praised then they will keep making them. And even if they don't Trek couldn't get any worse off than it was after ENT was canned in which case I still have the entire library of Trek to enjoy.
I do remember someone saying some bigwig type person at Paramount was a bit disappointed in the numbers, but that never made sense to me. I mean, a Star Trek film sequel made a half a billion dollars, following on the trail of a totally revamped Star Trek movie also making a half a billion dollars. To me that sounds like success! I guess I'll never understand some executives.
After all, how many times have we seen sequels crash and burn? To me, getting a billion dollars on the box offices of two movies is stellar and to be celebrated!
From what I have heard, it didn't meet projections, which pretty much means they were hoping to make more money. I have friends who work in Hollywood, and have a better idea of how the industry works. One of them said that while Paramount might have wanted to make more money (they always do, folks) it wasn't a "failure" by any definition of the word

Edit: in an odd twist, an add on another website I'm reading has a screen grab from ID with the title "10 biggest ever box office flops and bombs." I must define failure much differently...
