This season picks up from where the first left off following a short time skip.
It’s nowhere near as focused and mostly just comes across as a random assortment of ideas thrown at a wall: Arbitrary resurrections, sudden sci-fi elements (though some might consider those a positive considering the series didn’t start off very superhero-like), some questionable costume choices, and the appearance of a ninja army (not quite as bad as Daredevil‘s, but still pretty bad).
I’m generally not one to mourn a loss of realism, but here that was in a sense the show’s defining trait. The corporate elements don’t work well either. As for positives… well, I guess Laurel’s arc is solid enough and I’m certainly not sad to see the (apparent) end of Thea’s questionable romance.
