Just finished watching this. I only caught this on DVD from Amazon so I'd never been influenced by any TV screening. This series takes a while to build up into the story, and the lead character, Charlie, does come over as a piece of self-interested, whiney, idiocy at times, with the typical seedy, low-life Private Investigator chip on his shoulder, but as you reach the climax you finally "get it" with his background in the "Alphaverse" and it's oppressive social environment, even so, he's not all that sympathetic a lead at the beginning.
As I said the story takes time to develop, this is 20 episodes with one principal story arc throughout, which probably contributed to its lack of mainstream exposure around the world, so settle down to enjoy the ride to a fulfilling climax.
The different "Verses" are nicely-realised, with distinctive colour styles for each, from twisted, dark, shadowy Alphavers, reminiscent of "Blade Runner", through our very own "Betaverse" to the richly green "Gammarverse", and beyond...
It's a pity there was no second season, although the scripts were supposed to have been written, perhaps one day?
