As mentioned above, the FX was affordable but the prime FX companies were not available at the time for post production. As for the teaser of V, I thought it wasn't effective enough to engage me into the plot. Maybe if I saw a ship who attempted to travel through the Great Barrier and failed for whatever reasons being it would've hooked me. I would have some concern because the new Enterprise will eventually face such a giant challenge, which in the proceedings of the movie it wasn't much of a challenge to get through.It has some highly effective moments of cinematic direction (Sybok riding to J'onn in the pre-credits).
It has very good scenes between the characters Shatner had to care about. Aside from the campfire, Kelley is amazing in McCoy's flashback.
And Luckinball is good.
But plot poor, treatment of supporting characters poor, and the big fx shots Shatner wanted but couldn't afford would be dwarfed by modern CGI, remembered only as "They did that before CGI?"
I would've love to know McCoy's personal perspective of God, and how it effected his relationships with his family; whether going into the alien medical field cascaded his beliefs? What would it mean to him if he could actually meet God? How would those ambitions be an obstacle to Kirk and the mission? The concept of finding God is a lofty one but you have to have the right kind of creators to make it work. Shatner, unfortunately, was not that guy.
