Just like when Barry crossed over to Supergirl's earth. I am letting everyone here crossover to the Supergirl wiki to see my reviews of the show. It is pretty good so far as i have only made it to episode ten. I will release part two in a few more weeks. Don't worry about episode one, i already made it on this wiki.
Hope you enjoy my reviews and i will post the other episodes including the crossover soon. Credit to Nobody700 for inspiring me to do these reviews.
