I always took it as the bridge in TSFS was mostly "powered down" due to the automation system and the lack of a large crew to run Enterprise. I loved this movie! (Even Reverend Jim Kruge) The only thing I coulda used less of was the "rainbow warp effect". It worked so well dramatically in WoK and I guess they thought they had to re-use it again in TSFS. I very much agree that ST III is a very underrated entry into the Trek saga.
