If I was forced to choose between my favorite Trek, it would be TNG(narrowly edging out TOS). It to me was the absolute perfect Star Trek series. Why couldn't 'Discovery' have taken place 20 years after it? The actors from that series are age appropriate so they could easily be written into a "special guest appearance" episode. They could have even have incorporated some of the smaller bit players in to larger roles(example: ensign Sonja Gomez now Chief of engineering on a star ship). But I don't want to dream about that, the damage is already done.
