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 »

If you remove all the scenes containing Olicity
3 December 2017 | by omkumar19See all my reviews

This was a solid episode again, and it was fun. Action and CGI was impressive and the staff deserves appreciation for that. However, I am gonna only rate this episode as a 6 because Olicity. If you take that out then its a, 9/10 episode.

The constant pathetic attempt by writers to shove Olicity crap down our throats is just unbelievable, who the hell interrupts their friend's wedding twice. Anyway, we have all given up on Arrow anyway, I'd continue watching Flash and Legends from now on.
