Power of X builds upon the story, showing Sinister in all his glory. The first half is actually pretty great to get to see Hickman's take on Sinister, a long time villain of the X-Men world. The rest of the issue deals with the build towards what the X-men plan on doing to prevent the terrible future that is to come but it's not as captivating as the last two issues. Overall still solid. A 3 out of 5.
