What was the point of the Pah' Wraiths???
Deep Space Nine in the 1st 3 seasons managed to develop a sub-culture of a pseudo-Tibetan Buddhist Monks in outer space. Layers, and layers of an interesting society who can garner and dictate a lot of social politics within Bajor, the Federation, and within DS9.
The Pah'Wraiths were a complete slap in the face of everything which was done successfully; it was a cartoonish, cliched form of catholism, if there's a God, then there gotta be a boring Satan

that never fit with the narrative of the Bajorans. Also having these stupid cliched elements stripped the complexities of 2 of the great 3 dimensional, Star Trek characters ever made Gul Dukat, and Vedek Winn, and made them into 1 dimensional evil villains.
In the 1st 3 seasons, it was their words and presence was all these characters needed to manipulate, and create discourse in the stories; steering people who wouldn't hurt a fly will now do some terrible things. Based on the complex ethics these people hold and believe.
4th thru the 7th seasons, those characters are now uncharacteristically, lowering themselves by visually getting their hands dirty, even when they have the upperhand. Those characters became so predictable, irrelevant, and laughable the writers ended up doing the only thing what was left to sh*t on them completely was to have them f^ck themselves.
I wish those writers would have left the religion, the Bajorans, and the Cardassians alone, and continue their boring war arc with the Klingons, those wannabe T-1000, liquid aliens, and their Predator like soldiers.
