Goofs

When Barry introduces Supergirl and she levitates to prove her alien nature, she also uses her heat vision to burn her family crest into the floor behind the rest of the team. No one looks at what she's doing, only looking at her, which they should as, from their positions, her heat vision would have had to cut through Professor Stein. The heat-vision effect was added in post and not originally scripted. Later in story-time, Barry has to explain Kara's heat vision to Oliver quickly in battle, which he should know from the aforementioned introduction. Complicated by that explanation being depicted twice. See more »

Amazing (Crossover wise)
30 November 2016 | by (India) – See all my reviews

Amazing episode. It is so exciting to see all of the superheroes/supergirl's team be united this way!I won't say best episode because for me the best episode of this season so far was last week's (episode 7) episode. There is only one thing that I didn't like

  • it is Cisco's attitude towards Barry. He is taking it way too hard on
Barry.I can understand that he is angry but come on Barry suffered a lot too!How does it feel to know that even if you have power you have watch your mom die in front of you. He sacrificed his own happiness in season 1 final episode and did not change the timeline (may be Cisco didn't remember it?) Watching your father die in front you season 2 was too much pain to handle and he did made a mistake but wasn't he punished for it too when he have to beg his worst enemy to kill his mother AGAIN!!!I don't know much about comic books but I watch this show mostly because of Grant Gustin's Barry Allen and one of the attraction of this show is the bond between Barry/Caitlin/Cisco (which seems to be damaged permanently) so it is very hard to see the treatment Cisco is giving Barry right now :(
