Disappointing except for the two leads
3 April 2016 | by siebertws13See all my reviews

Admittedly, I've never watched "Supergirl," but this episode would never make me come back. Only watched because my 13-year old son & I are fans of "The Flash," but he and I both agreed it was a "meh."

Only good thing was the chemistry between the two leads, who are both charming and very appealing on screen.

Otherwise, it really felt like warmed-over "Flash," very similar opening credits, a cranky authority figure, a super secret scientific support group, a (much blander) interracial cast. And Supergirl - - she sure doesn't seem very "super" and gets her butt kicked a bunch by seemingly lesser bad gals. That was weird.

I did get a kick out of seeing Frasier's pushy agent as one of the villains' aunt. She's a great, brassy actress, whoever she is.

Not terrible, but nothing special at all. Very common TV.
