I actually really like the Excelsior bridge. The different proportions and scale, and black chairs and consoles, gave it a very different feel to the usual Fed ship. Most non-Ent bridges are in fact just redresses, IIRC.TSFS. The Excelsior bridge was trash; the Grissom bridge was just a redress of the Enterprise bridge; and the spacedock was awful (though I did like the dining/lounge area next to the docking port).
The final location on the Gen planet looked like a set, but previous bits were convincing, if obviously small in size. I think the problem with that final set is the way it was shot. More naturalistic light, more sense of depth in the photography, better blocking (positioning of actors), would have produced a much better result.TSFS also looks cheap for a lot of the same reasons, and the really obviously soundstaginess of the Genesis planet seals the deal.
While I like TFF I have to admit it has some very weak visual moments. Some of the ship shots actually look good, but a lot of them just look unfinished (I still find INS worse to look at in this respect). The moons behind Uhura are obvious a backdrop or projection, as they are distorted by the camera angle. Paradise City looks okay, but the action there was obviously all shot in a rush, as most of it looks unconvincing (I can't help thinking Shatner could have had a career in times of old making cheapie Westerns - De could have starred!). And note how much trouble they have aligning the phaser beams with the weapons during that sequence!
Some very good points.
And I LOVE the thought of b westerns as a directors outlet for shatner. He'd be perfect!
