I also indulged on Priest that Great Rumbler (edit : toku actually) suggested after my hate watch of Legion for more Paul Bettany-starring not-so-packed action & edgy Christian imagery and wow it's even worse, which is no small feat. It's pretty incredible to see something so underwritten coming from Hollywood, even the most mediocre schlock will come with some baseline story beats usually. Going sequence to sequence is jarring because there's zero flow to the story and writing, there's no buildup to anything and the timeline and geography gets legitimately confusing in parts (turns out nothing looks more like monochromatic flat desert than another monochromatic flat desert). The film can't handle parallel editing for shit which is a pity because the big set piece relies on it. That climax, by the way, will make you go "Huh wait, is that it ?".
It's really a lot of nothing stretched really thin made more infuriating by the director winking because he's withholding some pieces of the plot and lore (sorely needed) in the foolhardy hope of a big budget sequel. Overall feels like it was emergency edited / reshot in parts. Alternate post nuke retrofuturist western movie is no less valid than any fantasy pretext but there's no world building, it gets really silly you have Blade Runner cities, GPS and Old West pocket watches and phonographs in the same universe thrown at you.
Legion had all of the same shortcomings, but the tighter unity of time and place made it less noticeable. The only thing Priest has going for it is Karl Urban hamming it up and Brad Dourif making a cameo. Why even bother get Plummer to waste him like that ? Maggie Q is well... (Do you remember Maggie Q ?) and the young up and coming fresh face is the blandest thing ever. Phil Collins daughter too. You gotta feel for Bettany, sadomasochistic Catholic executioner is really a bizarre typecast to fall into.
