Very poor
The beginning is very attractive, Atlas being a powerful man close to a god. like Hercules was. We don't see major aspects of his personality. Half of story is a flashback and, at least me, can't see a climax and something to care about this.
The main reason to read this is the old vintage aspect which I find it cool. Next we have the cover which is glorious, the best thing of this comic!
Finally, I was very disappointed of the story. At the end the comic we are told an address where there were sent votes for a series of Atlas, but it seems that it didn't received many votes and it wasn't continued anymore. If it was continued this would be a great 1st issue, but for an one-shot it didn't meet my criteria at all!
