While not a massive 'refit' military aircraft and ships are upgraded all the time, as are commercial aircraft. This would be difficult to do in small bits and pieces with a ship traveling for years many lightyears from home, so perhaps doing all the upgrades every few years would make sense. How much is this done today? It's the main reason that military contracts are all cost-plus. Often the military changes what it wants several times while the aircraft/ship/hoodiggie is being developed and built. Specs change many times often before the first craft is built. When a bomber that was used in Viet Nam is being flow today, it has modern computer guidance installed, it's not running on the system it used in 1964. However, it often looks much the same from the outside. (I am a military-industrial complex brat. My father spent most of his life designing and upgrading military equipment, including, the last thing he did... the first system that shot down incoming missiles, which was done for the Navy. Reagan based his idea for 'Star Wars' on that system.) Concerning the ship's counselor, I suspect this has much to do with the actress being Vic's wife. Also, TOS has a very sexist feel that I suspect many people today aren't comfortable with. (I was not comfortable with it as a 'tween.' at that time.) That is not Roddenbury's fault, he wanted a female No. 1, but there was a lack of vision in the suits, and its one of the things that dates TOS to the 1960s. The introduction of this character allows the production to counter that problem without entirely reworking the rest of the characters. They are also giving Scotty a bigger role than in TOS. Background recurring characters work for some things and not for others. It would have made sense that Kirk would have been reporting to a particular admiral, rather than hearing from a different one with each order. Would it be wrong for fan films to correct this? I don't know that I had any desire to see what happened to Apollo, but I liked the story. The Orion Slave Girls did seem to beg for some updated twist. That is clearly our ideas intruding on those of the 1960s. It was a revisit, but it took something that was just a passing matter in the background and made it into a central story. Most dramas today have a story or two each year on the supporting cast. Usually, Castle focuses on Richard Castle and Dect. Beckett, but we get shows that focus on the other police officers once or twice a year. Those types of shows did not exist in TOS. I don't think the greater use of the character of Scotty in STC is wrong or out of place, it's probably a more realistic take on how the crew would work. There was no Chekov show, no Sulu show. Filling those in is also a modern update, but its one I have enjoyed from Phase II. Part of this I suspect is just how much you like fan efforts. I happen to enjoy them a lot.
