This is it folks! The beginning of when the Arrowverse crossovers turned into full fledged superhero extravaganzas! In this one the alien race known as the Dominators showed up to wreak havoc on our heroes! Luckily they have Supergirl on their side! And I have my good friend Mike Bean to talk about this one! We laugh about how they clearly hadn’t quite figured out how to work all the actors in but they still pulled off a fun and exciting crossover event!
