Another big disappointment was ‘The Ultimate Computer’ – the fleet that attacks the Enterprise were all originally reuses of the Enterprise because they couldn’t afford building and shooting a new model. What’s stopping them now? I would have thought seeing at least one new TOS design (it’s not like they don’t exist – try Franz Joseph’s old manual if you can’t make up your own!) would have been a given.
Still, seeing other Constitution Ships BESIDES the Enterprise interacting with each other is a cool bit of detail, because nobody would ever do that again because everyone thinks the audience is stupid.
