I understand about your point, but my point is about a story telling with the theme of "Boldly Gone Where no man has gone before", not about the exploration itself. I don't care about the exploration in gamma quadrant or delta quadrant or exploring 400 billion of planets. My point is that revisiting the same location (gamma / delta / or whatever place in Alpha Quadrant) won't give us a new Star Trek, but the same Star Trek with new actors and ships. Going to another Galaxy will refresh and expand Star Trek.
But well, it's up to you if you don't like my idea. I have already write my point here. Prolonging the debate will only make a counter productive result for both of us, because I have already explain everything here
