Here's the main problem: this version of the Suicide Squad just isn't that interesting. It's full of no name characters with no backgrounds and no characterization, and that doesn't make for a good book. Oh, Deadshots's good, and King Shark's funny, and Harley's great when she finally comes back on stage, but the other characters ... who cares?? 
 I was actually somewhat encouraged by the first issue in this volume, which offered some backstories for everyone, but that was the height of characterization in the volume, and pretty soon after that we were back to the fighting. 
 The mini-arc that followed was especially frustrating, because it was a big crossover with Resurrection Man that only made partial sense without the full context. But the very long fight against Basilisk wasn't much better. Because, again: who cares about these guys? The final issue tries to provide some context, by explaining Regulus' backstory, but it's too little too late (and it's a bit dull too). 
 So, in summary: boring characters (with some exceptions) and boring villains having boring fights. This definitely isn't John Ostrander's Suicide Squad.
