Nice story.
While I grew out of my VS phase (we used to debate what ships are more
powerful back in the DAY !) I say that I recommend you watch Star Trek
Voyager.
Simply start in S4 and keep going.
If you don't know Star Trek is divided into series like
TOS
TNG
DS9
VOY
ENT
and then you get into the new stuff of Discovery and Picard.
The new stuff (Discovery and Picard)
Are like every other modern show where you need to watch every episode
to get 1 story. They are terrible. I liked the episodic nature of the
old shows.
Most people know about the TNG era (TNG, DS9 , VOY)
TNG and VOY are basically the same and episodic however they have a
light continuity. Meaning if characters die they die for good (you know
it when you see it) excluding all the fake outs and resurrections the
show has.
There is some continuity since when a faction or character shows up
episodes later the characters behave and refer to the previous events.
Only its not super crucial I think even if you did not watch the episode
you can understand it from context. Think of it like Jabba the Hutt and
Solo talking about previous events in Star Wars you don't really need to
know what happened there.
Most people will recommend you watch TNG however the first episode of
TNG can be boring so you either skip them or power thru them to get to
the important stuff.
There are 2 parter episodes however I don't see anything wrong with that.
DS9 is different so be warned.
ENT is episodic however deeply problematic and in later seasons it gets
more continuity based story.
For the movies I recommend you watch Star Trek 2 The Wrath of Khan its a
really great movie only watch the original 1982 movie not the after 2009
stuff.
The Wrath of Khan refers to a TOS episode however its not that
important. You seriously can watch the movie alone and realize what its
all about from what the movie says (bad blood between 2 characters one
did something to the other).
I argued for Star Trek back in the day because I grew up on Star Trek
(TNG era) I watched the Star Wars movies however Star Trek was the
series I watched so it was more prevalent in my life. I agree on your
opinion that the OT is good.
