Up Up and Away Super Friends and DC Comics Fans , Here is my review of Supergirl Season 2 Episode 4 Survivors 1st a description of the episode : While investigating the murder of an unregistered alien, Kara and Alex find an alien fight club run by Roulette; Hank tries to get to know M’Gann better; Supergirl begins to train Mon-El. Now on to my review of the episode Warning Full Spoilers To Follow , Wow Survivors was good , action packed , intense , scary and emotonal. Supergirl , Alex , Maggie and The DEO really had their hands full dealing with Roulette and here Alien fightclub. This episode had so much from Supergirl , to J’onn , M’Gann , Alex , Maggie , Winn , Mon-El and The DEO to Roulette and her Alien Fight Club it had it all. Roulette was a good baddie for the episode and here alien fight club was so scary and terrifying , Snapper is still mean a bit of a hard nose to Kara at Catco. The Alex and Maggie scenes this week again so good. The J’onn and M’Gann scenes where so emotional and powerful you can tell they are the last of their kind. The fights in the episodes with Supergirl , J’onn and M’Gann vs The Alien monsters where so good. The Winn and Mon-El drinking scene was so good and the Supergirl and Mon-El scenes where good. Good cameo also from Lena Luthor in this episode. The ending cliffhanger wow M’Gann a White Martian that came out of no where. Overall I give Supergirl Season 2 Episode 4 Survivors a 9/10 a great episode and can’t wait for next weeks episode titled Crossfire. Up Up and Away!!!
