I feel like that as well (though my vote was more in the "B" range). I think STID very much succeeds as an incredibly fun spacey-wacey action-Jackson blockbuster, but like ST09, it does not hold up very well under intense scrutiny. That, of course, turns off a certain set of fans. Me, I think Star Trek should be fun, because that is, in fact, how it started: as a space-set adventure show. But as a fan, I also very much believe in the franchise's overriding ethos of telling big, idea-based stories, which is where I felt STID fell a bit short. I definitely didn't find it to be a failure, mind you, but I feel like a bit more polishing to the script could have brought that balance you speak of. For me, the Trek film that comes closest to achieving the cerebral vs. action balance is probably TUC. Its political allegory is not so subtle, to be sure, but I feel it's woven in quite well with the story, which has stakes for the characters that make it involving for the audience addition to throwing in some (reasonably) thoughtful commentary on the early uncertainty of post-Cold War international relations. I feel like Trek could do something similar with terrorism today, and had a good chance with STID, which did include aspects such as the militarization of Starfleet, etc., but it didn't all quite come together as well.
