This episode was crazy! Omg, all he twists too were some of the best parts. For example i never thought earth-1 would go and all of the characters except for the paragons are dead! That makes for a great climax in the coming parts... are they going to fight at the dawn of time like in the comics? Is reverse-flash gonna show up? Who knows what the crisis has in store for us... great episode though and easily the best of the crossover. 10/10
