Yep, I realise that. But the impression I got (and I believe it to be reasonable, if not accurate) was that off screen elapsed time was on the order of hours rather than (at least) the couple of days it should have taken for the ship to get to Vulcan.
These kinds of thing take me out of the movie experience because it seems to be as if the writers don't care enough to have a semblance of reality to things like transit time.
I know we are talking about Science Fiction here, but if you do not treat things like the time it takes to travel 16 Light Years in a realistic fashion that correlates to previously established in-universe facts, then to my mind we venture into Science Fantasy, where anything can be changed to suit the story and gets no rational explanation to back it up.
Star Trek has always been more Science Fiction than Science Fantasy.
When I want Science Fantasy, I'll pop my Star Wars Blu-Rays on the telly.
