There should always only be one chair in the center of the bridge, and it should swivel. It's iconic. The Enterprise-D and most other TNG shows broke that rule, which was bad.
Not only that, but the original bridge design happens to also be the most efficient. So efficient that it was studied by our real life U.S. Navy. TOS, the TOS movies, and DS9 (on the Defiant
) got it right and stuck to that. But TNG, the TNG movies, and Voyager
unfortunately moved away from it and it made their bridges seem far less efficient, IMHO.
