I like Star Trek because of the hopeful future it depicts, the exploration I would love to experience, and the well developed characters.
Episodes are varied, one episode might focus on a side character's love life, where another might be a battle against a superior foe that feels like a Das Boot adaptaion.
I recommend Strange New Worlds, it's a return to episodic storytelling, it's got great visuals, great actors, and the weakest episode is better than The Next Generation's average episode.
I recently introduced a friend to Star Trek with SNW without explaining anything and it did a great job of introducing the setting and itself
That's why I recommend SNW over TNG for newcomers
