Steel catches Supergirl when she falls from orbit, producing an explosive impact effect. While the ground directly beneath his feet is bare earth (as opposed to the grass around him) and there's a ring of dirt around them, the area where Steel is standing on is level with the rest of the ground and Steel's feet haven't sunk at all beneath the surface. At a minimum, his legs should have been driven into the ground by the force of the impact. See more »


Oliver Queen: Thanks for your help.
Leo Snart: We're not done helping yet. Our enemies are still on your earth, Ollie.
Oliver Queen: Don't call me that.
Leo Snart: Give it time, I'll get through that crusty exterior.
Sara Lance: No, you really won't.
Leo Snart: I was talking to you.

User Reviews

Far far left writers, filled with conservatives are Nazi references.
13 August 2018 | by jasonbourne-02272See all my reviews

Riddled with Nazi bad guys, with their slogans of "Make America Aryan Again", using Antifa (Far Left Hate Group) slogan of "Punch a Nazi" over and over and over.. (a dog whistle for attacking conservatives). Tired of politics and anti-conservative messages, and outright calls for violence against them.

Additionally, earlier the "Nazi' version of super girl explains that they are more powerful because of Meritocracy.. because .. you know, capitalism is evil and should be associated to Nazi's.

I'm done with this show and the CW Television Network.
