Conceptually, the idea isnt bad, it's just over-done. And with the Grayson series still fresh in everyone's minds it's not a surprise that DC tried another big departure with the character. But it's not the creative stuff I take issue with (I mean, Ric has been awful from what I've seen, but that's just how it goes sometimes).
I didnt watch it until it was on blu-ray (my daughter saw it at Target and had to have it), so the run time wasn't a problem for me, though I can imagine it was annoying asf watching it as each episode came out. And I stopped watching the CW long ago, so I had no idea anything had been erased until long after the fact. Still, on its own, it's not a bad show at all and could easily be the ground floor of a proper mythos for Vixen.
Since I don't watch the CW and the art styles are close, I just pretend in my head that it's part of the Young Justice universe.
