The Flash?

There's a crossover happening at the moment and I love it. All of the heroes from The Flash, Arrow, Supergirl and DC Legends of Tomorrow are teaming up to fight some aliens :yay:
On a side note, in my nerdy opinion it's definitely worth watching The Flash as it's a great show with some nice messages and action but what does annoy me is that every season the antagonist seems to be a speedster and the storyline becomes slightly repetitive. For someone who is "the fastest man alive" Barry Allen sure does have some competition.
