Well, I'm having a sneaky look on this now...it's an interesting piece and a shame that the edit is limited to such a low number of available sources. It needs slightly less Kirk material as his part in the story seems quite sudden or perhaps a new way of introducing him. Because of this, Sulu does seem to be a bystander rather than a main protagonist. A widescreen presentation would have been better given that the pan and scan version of STIV chops off a lot of the pic but a good effort nonetheless.
George Takei did lobby for a number of years for a Sulu TV show but I think he's moved on from that now. A nice little peek into 'what if....' territory. Needs a little more polishing but a good effort.
