This volume is immediately on top of wrapping up the plot and answering questions, so fortunately nothing included feels boring or pointless. 

Exactly how and why the gang's parents got involved up in becoming super-villians is finally described, and while the given story is definitely weird it's solid enough that I never questioned it when I read the series previously.

However I don't like the outcome of the mole plot even while reading it after the original wound of betrayal has healed, and feel that there was a way it could have been done differently so the child in question was redeemable.

The Runaways still aren't very strong fighters so if you're hoping for some sort of epic showdown between them and their parents you're in the wrong place, but honestly I think that's better than trying to convince readers that they have the skills to defeat super-villians after only a few months with barely any training. 

In my opinion this is satisfying ending to the original series that doesn't pretend everything is unrealistically perfect once evil is defeated. By the end the Runaways are still runaways, and still setting out untrusting of adults and alone as their own new family.
