For me, it's just that I'd rather see new stories. We've already got the existing stories to watch. That said, sure, I'd watch modern adaptations.As I've said before, I'd actually really like to see someone rework classic TOS episodes with fresh scripts (and maybe some story changes as well). I'd just love to see existing stories readapted, and how they might be different from the 1960s versions.
That seems to be anathema in Trek fandom, though.
