It's been great! The fact they have had Firestorm..... (which in the old Flash comics was always a backup story) as well as putting together the Rogues. Then having Eobard Thawne and not stringing it out for 3 seasons before they reveal his motives.
I'm pumped to see another Arrow crossover.
And they're spinning a new show off with Brandon Routh as the Atom, Firestorm, Hawkgirl and Rip Hunter.
DC has a better, more fun established universe on the CW then they do in the movies.
