If you are interested in this product because of previous offerings from Vigilance Press, such as the Oktobermen, and you want some interesting villains to throw in your campaign, this isn't what you are looking for. But you still want this.
Why? Okay, if you never, ever have any kind of romantic interactions in your campaign, maybe you don't want this. But if you do, there is a lot of really nice information in the product. There is some pretty sound general advice about romance in supers campaigns, new advantages and features for Mutants and Masterminds that have to do with romantic interaction, and there is even a subsystem for determining romantic progress, as well as details on what happens when heroes get a broken heart.
Now, I've heard people say, across various game systems, that you don't need rules to roleplay. I agree, but having good rules that aren't overly intrusive and reinforce roleplaying certainly doesn't hurt when it comes to nudging someone that might not take time to woo an NPC to do so.
The actual NPCs are fun as well, but not really villains, and barely heroes. They are a nice addition to the campaign if you have a game where you explore superhuman celebrities that are not strictly the crusading type, and they have a few nice, subtle applications of the rules detailed in the supplement applied to them.
The unsung hero of the piece is the poor guy that gets the least details on him. Just the bit about Serval's rogues gallery makes me want to see him get his own write up, and I have a feeling that his rogues gallery, further fleshed out, would make Flash's rouges look like the League of Assassins by comparison.
The art is very nice, definitely on par with the upper tiers of RPG publishing, and the layout and look of the stat blocks is very sharp. I can't recommend this if you really don't have any romantic notions of any sort in your campaigns, but if you do, or you want to explore adding it, or you just want to see how mechanics that reinforce roleplaying interpersonal relationships could look like in Mutants and Masterminds, I don't think you could do better than this.
