It wasn't an entirely terrible effort and had it's moments. The biggest problem I had with the show was that it couldn't seem to decide on an identity for itself. You had the pre- and post-Crisis amalgamation, Helena being too much of a standout character (resulting in the show coming off as more of a solo focus rather than strongly emphasizing the cooperative aspect of BoP), whatever the hell Black Canary-lite was supposed to accomplish and lastly, the over-reliance on the presence, or at least idea, of Batman (whose utter abandoning of Gotham put me off anyway).
The hint of romantic relationships they established with Helena and Barbara, respectively, was stunted (especially in the case of the former) and I didn't really care for how the mother-daughter 'legacy' of Carolyn and Dinah Lance was executed. I think scraping the re-imagined stuff and using more of the dynamic incorporated in the comic title would have been a better direction.
Its noted flaws aside, some of the sequences and interactions they pulled were good to see. There were hints of what I like about these characters sprinkled throughout the varied episodes. Seeing a live-action Batgirl, other than Yvonne Craig whom I love, was nice, even if only in flashbacks, the Shiva ep and the last show. I think Dina Meyer as Oracle was probably the strongest thing about the show. She did a great job with Babs. Huntress had some decent action sequences and I really liked Lori Loughlin's appearance as Black Canary (they should have just used her in the lead cast and spared us the daughter character). They pulled the plug on it rather suddenly, but still managed to have a proper series finale. In the wake of those 13 or so episodes, there was some untapped potential that could have resulted in something much more enjoyable.
