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.
