Those are standard comedic devices, why not just identify them as comedic? The only thing I see that might qualify as camp are the over-the-top performances the crew puts on for the androids in "I, Mudd." The use of the word is also incorrect, as far as the dictionaries I have access to. Going back to the OP: All shows age, and all will look dated to younger viewers to some extent. TOS happens to be the eldest Trek. If a viewer doesn't have enough to identify with or connect to, they won't like a show that's so different in look, style, pacing etc. from what they're used to. With that in mind, TOS is quite remarkably ahead of its contemporaries in the amount of attention it generates, going on 50 years later.
