I'm not familiar with that title. Sadly, I have entirely fallen out of the comics world, though I'm never unhappy about recommendations.
Kingdom Come was, in many ways, a "slippery slope" title - people started using the imagery and stylistic tics in that series without understanding why they were so effective. Much the same deal as with the crap which attempted to cash in on the "mature" storytelling of Watchmen (ignoring storytelling basics and using sex and violence being, ironically, the least mature kind of comic imaginable). You have to read it, if only to understand where so much of what was to come was gaining inspiration from, and notice the influences in it.
