The last season of The Flash was pretty strong.
I will say, beyond starring a blonde female lead and being a fairly light and optimistic Superhero show, Stargirl is quite different from Supergirl.Stargirl looks way too much like Supergirl, which I only tolerated due to the now defunct Batwoman tie-ins. I might give it a chance in a couple of months when I'm not so p***ed off with the CW for sh***ing all over my favourite comics character. It's DCU, not CW anyway, so maybe one day.
