V is pretty bad due to lazy scriptwriting:
* "The Great Barrier" was a silly plot device, and the idea that the Enterprise could travel 25,000 light years as if it was a quick run to Alpha Centauri foreshadowed JJ-tier movie science
* The concept of Sybok healing people's "inner pain"

and this somehow making them abandon their sworn duty and become fanatical cultists was dumb (but maybe plausible to upper-middle-class Californians, idk)
* The Reddit-tier understanding of religion was vintage Roddenberry, who (like a lot of mid-20th century liberals) seemed to disapprove of God on the grounds of "don't tell
me what to do, Daaaaad!"

Unlike Philip K Dick or Gene Wolfe, Star Trek has never had anything interesting to say about religion (Ben Sisko: space prophet was also stupid) because it's a bland materialist utopia written by nerds, but at least "why does God need a starship?" was a great line.
