It might just be that people like seeing romance in movies. And honestly, it was a nice change of pace to have it be somebody other than Kirk.
Do you not think it dumbs down Spock to our level and makes him less interesting?
No. It makes his character arc an interesting allegory for "coming out" (like many other allegorical moments in Trek). Is it the most intelligent and moving such moment in film history (or even in Trek history)? No. But it was an interesting take on a character that I thought would prove the most difficult to do differently from the original.
I also think (my own speculation--no rumours or any other sources to back this up) that a lot of the flaws of the story (I have no complaints about the technical choices and effects used in the film--even the lens flares don't bother me a bit
) come from the writer's strike and the restrictions on re-writes, coupled with the late change in release date. If re-writes had been permitted, some of the things I found clunky might have been smoothed over pretty easily and had the later release date been known sooner, it would have been easier to do some of those changes. As it is, it wasn't perfect but it was quite fun and enjoyable nonetheless--and that's all I've EVER expected from Trek. Any "thoughtfulness" and "serious themes" that ever cropped up (and they were a lot more impressive when I was 12 than they are now) were and remain a bonus. If I want "deep and thought-provoking cinema", I look elsewhere. Given Trek's overall track-record, so should everyone else.
