Did You Know?


The foot race between Supergirl and Flash at the end is a nod to Flash Rebirth # 3 in which Superman and The Flash (a resurrected Barry Allen) also do a foot race. Superman is able to stay alongside him and even boasts he's beaten The Flash in previous races but Barry finally admits those races were for charity and then blasts past Superman, leaving him in the dust.

The Flash: [speeding around the DEO] Yo, this place is amazing, all right? Is this a spaceship?
Supergirl: That's actually my spaceship.
The Flash: I love this Earth. Hey, Winn, can I get a picture with this bad boy?
Winn Schott: Oh, yeah. Sure.
The Flash: Awesome.
Supergirl: Winn. Winn.
Winn Schott: That's probably not a good idea, dude.

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.
