If you’re a kid, start with Prodigy. If you have a tiny attention span, start with Lower Decks. If you’re used to mainstream modern TV, start with Strange New Worlds. If you can tolerate 90s TV, start with TNG season 2. If you love old TV, start with TOS.
The best entry point is going to depend on who you are. There’s lots of diverse Trek for different kinds of people.
