Be ready for mid 20th attitudes, special effects and theatrics style production…and camp.
At nearly 60 years old, TOS is actually more bearable for me again than it was watching it in the 1990s - 30 years in it seemed cringey.
But what it does have is wild and trippy Star Trek energy, the kind of vibe SNW is recapturing for modern audiences. Lower Decks too.
TNG was going for a more professional cerebral vibe, and less fun. It was a nice contrast to TOS, but it’s nice to have something new with that vibe. Voyager really leaned into the weird in its journey across the Delta Quadrant, but played it straight more often than not.
