I am so happy I decided on a whim to binge “Arrow” a few months ago. Because I got sucked into Oliver Queen’s universe, I was ready to take on Barry Allen’s in “The Flash” when that premiered. If any “Arrow” fan isn’t watching “The Flash” or vice versa, I highly recommend you fix that immediately. Not watching one of these brilliant shows would suck some of the fun out of this entertaining crossover episode.
