Ah, I wondered if these trailers had been spotted on here! TMP one is pretty good with maybe two hiccups. Firstly are dialogue sentences that are set up...and finished dramatically; but the pause between the setup and finish are too long. What makes it more problematic is when the dialogue of the Epsilon station guy says "It measures...my God...!" and it's left hanging. So some of the other sentence setups are left too long to resolve, but the Epsilon guy has shown us they won't. And then there is a resolution that's been delayed too long.
That Wrath of Khan trailer is just fantastic, though! Very effective the way the music builds and builds, and the editor finds flash moments that neatly complement that build. The oscillating moments in the music are cleverly and playfully matched with stuttered phaser fire and the flashing of near-explosions (and Kirk vibrating with fury at Khan!). I've watched many fan trailers for fun, and this is one of the better ones that I've seen (or at least, one of the more fun ones for me personally).
I hope they'll do TSFS and TVH, too, I would really like to see what they can come up for those.
