Excellent premise: vampire post-epidemic society trying to deal with the scarcity of blood, ethical ramifications of keeping the remaining humans sedated for blood harvesting, technical challenges like adapting infrastructure and vehicles to be sun-proof, etc.
The only thing I clearly remember is the premise, cuz the plot, characters, dialogue, action, etc. was all dog trash
Actually, I do remember how badly it mangled the social commentary on the vampires who couldn't afford blood. Perfect setup for depicting the inhumanity of artificial scarcity and they botched it.
