A Lovecraftian tale, heavily influenced by Alien and set in the Wild West of the Cursed Earth. How could this not be a great story?
With several issues to slowly build suspense and malevolence you really get drawn into the peril of the situation. As the threat comes from an unknown alien literally anything can happen making the outcome uncertain. A high judge bodycount ups the stakes too.
The terrifying part is when Dredd is possessed by the creature forcing him to kill innocent judges. Committing any crime is an anathema to Dredd and being totally out of control is a really frightening prospect. This is his worst nightmare.
Ezquerra is in his element with the Cursed Earth, muties and alien life forms. This is very much his forte.
