Critic reviews for Medusa

As it turns out, last night's Supergirl "Medusa" only played a minor note in our crossover symphony, but created enough intrigue and set the table for what will happen throughout the week on CW.

"Medusa" is the episode that sets Supergirl back on track. After a couple of episodes that were often boring, everything about this episode was engaging.

For the majority of Supergirl's second season, we've been watching several relationships develop, across the board of the romantic, familial, and platonic. Last night's episode "Medusa" added fuel to some of these kindling fires.

I think we have the makings of a really interesting dynamic between Lena and Kara, and I'm curious to see where it goes from here.
