As someone currently on that journey, I’m thinking it’s well worth it! I started with TNG since that’s what I grew up watching and I’ve made it as far as the last season of ENT. Everyone talks bad about VOY and ENT, but honestly I think they’re great too in their own ways (although TNG will always be the goat in my book).
I’ll also add that part of what got me so hooked on it was listening to the podcast The Greatest Generation along with it. The extra running jokes and silly headcanon stuff really added a fun extra layer to everything! Helped me get through some of those rough early episodes too.
Everything is a lot of Star Trek! (but you should really watch everything eventually) I recommend tackling it one series at a time, and it will go by faster than you’d think,
My wife and I started with Star Trek: The Next Generation (TNG) and I think it is a great place to start!
After that you could watch Star Trek: Voyager (VOY) or Star Trek: Deep Space Nine (DS9). DS9 being one of my favorite pieces of media ever. I love it so much. 🥲
Or if you want something more modern you can start with Star Trek: Strange New Worlds (SNW). The second season airs in a few weeks, and I hope it’s just as amazing as the first season!
