Did You Know?


The first full Arrowverse crossover to include the Supergirl episode in the actual plot of the crossover; the previous year's Invasion! storyline only included a brief teaser scene at the end (which was repeated in the episode of The Flash that followed) and a few brief teaser shots of Team Flash's attempt to reach Kara throughout on the Supergirl side of things, while the year before that the show was on a separate network and unable to cross over at all. Supergirl and some of the other characters have been included in individual crossover episodes, but those events took place entirely on one show ("World's Finest" on Supergirl (episode 1x18) and "Duet" on The Flash (episode 3x17)) with maybe a teaser on the other for continuity.

Nazis serve their purpose.
29 November 2017 | by rasp13See all my reviews

Caught your attention didn't it. Hear me out though. A lot of people are complaining an asking why Nazis what is this 1985? For now Nazis serve a purpose in super hero shows. They are a human, Earth based enemy, where viewers don't get upset if the good guys hurt, maim, or even kill the human. The studio doesn't have to come up with a machine or a random non-humanoid alien, they can have disposable humans with a Earth based plot. Even the Avengers use them to be beaten to a more extreme manner. Super Heroes can kill humans, if the humans are Nazis.
