To be fair, Person of Interest's initial setup (and the one they're recently going back to) is mostly just the original Dinah/Babs BoP dynamic with Minority Report thrown in there. And with predictive analytics getting more and more hyped up in trw, it becomes difficult for a book with Barbara and Dinah to avoid that comparison.
I just picked up this issue after skipping the last couple (the store didn't get in my Transformers so I needed a fill in). And what an issue! First of all, the art is stunning. The way AI Barbara became increasingly more pixelated and glitchy as the issue went on was fantastic. And the way she echoed Batman in the flashback was really cool. I just wish Tarr was drawing the new Black Canary too.
