Golgo shows up, says little, gets the job done, maybe fucks a chick and then everyone around him throws their hands in the air and says "holy shit! Golgo is the most amazing and godly person on the planet!"
There's very little in the way of animation, mostly it's just people talking until the money shot, and the art is nothing too great although it doesn't look QUALITY. Just plain.
All that sounds like a bad thing but there's a lot of unintentional humor to be had. Golgo nonchalantly reading the newspaper while the police sack his apartment looking for his gun? And then strolling out the door because he is just TOO FUCKING AWESOME to ever be arrested
TLDR: If you have the right mindset it's fun.
