>>420221093You can start with the next generation, but there are some original series episodes that you should also watch, so you have a bit of context for some TNG episodes or DS9 episodes if you ever watch it.
S1E14, S4E4, S2E10, S2E15, S3E2
There are more good TOS episodes, but these are the ones that are important to eventually watch for the context. I just quickly scrolled through the episode list, so there may be more.
