If u are DC’s fan then u will love to watch this tv series since DC movies are not so popular . if u start watching this tv series u aslo prefer to watch arrow, Supergirl and legends of tomorrow.Aslo abut flash u will like all kind of scientific craps and aslo villains and reverse flash is the best of all. all the DC tv series are interrelated to each other . flash is the best DCs tv series . u will also find interest in season 3 because the villain is speed god "savatar". but there is no connection to justice league which make me ire. but till I prefer to watch this tv series.!
