Say what you want about the filmmaking as a whole but at it's core Trek V at least tried to be about something -- "maybe God's not out there, maybe he's in here..." A quality most of Enterprise and especially Trek 2009 seemed to put on the back burner in exchanged for cool FX and titillation.
Sure, it's execution can be debated forever, but I will argue that the section of that scene in the observation lounge with Kirk urging Bones "...you know that pain and guilt can't be taken away with the wave of a magic wand..." is one of the best written, best Shatner performed Trek scenes there is.
The concept of a fundamentalist converting followers into hijacking a ship for a religious crusade would probably resonate more powerfully in today's world context as well.
If done the right way, that is...
