This actually isn't that terrible writing wise. I mean the notion of governments wanting to annex Hell (which they won't officially call Hell mind you because that might be offensive to the local denizens) and get mineral rights. That's pretty interesting in and of itself.
The notion of super heroes, angels, and demons, all coexisting on the same earth is quite rarely addressed. (Zauriel from Justice League occasionally sparked this, but it's rarely addressed by anyone outside the occasional story with Mr. Terrific as far as skepticism goes). For dimension hopping oddballs, Hell would just be amongst the myriad of scientifically reachable places. I would have liked to have seen this continue on in that vein honestly.
Violator telling Bedrock what angels actually are actually are did make them seem extremely frightening. I've never gotten on with the image of the white winged pretty boys and girls who are full of light and fluff, as popularized by a culture vastly ignorant of its own holy books (and paying even less heed to historical connotation of them). Angels were originally described as quite terrifying and inhuman. I like it when people remember that in some form or fashion.
