I am NOT an Elvis fan, but find him tolerable. Agent Elvis is actually pretty cool. Lots of cursing, violence and drug usage means this show is not for kids, however adults that appreciate crude humor and sci-fi with a touch of nostalgia will appreciate the mix of future and past cultural references. They go a bit overboard on the drugs and alcohol. Scatter is a little too human with the ladies and the amount he understands humans, but at least he can't speak English.
Overall I have found it to be entertaining and am ripping through the episodes at a good clip.
Uses comic book styling during the action scenes, which is reminiscent of Batman the live TV series and several other cartoons. Worth a watch if you like crude humor!
