This is really starting to shape up. Nice to see what was on a script move to actual production and then towards final release.
The trailer really captures what is going on. Plus the CGI is great. From the trailer you can tell there is CGI (or some other SFX), but only to move the story along (unlike, say, certain higher budgeted Sci Fi films that were released in the past 15 years).
I really like the music. It captures the tension without taking over.
And on a personal note, you have a devilishly handsome Chief Helmsman (albeit on the plump side)! But that's just me.
