In the final scene where John is is about to conclude the ceremony a man with light pants and a blue top is walking from left to right in the background, when the close up is focused on Iris. The camera changes to John, the person walking is a completely different person, and the man with the light pants and blue shirt enters the shot now walking right to left. See more »

If you remove all the scenes containing Olicity
3 December 2017 | by See 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.
