Alex Danvers: Supergirl, you struck an agent of the United States military.

For those who don't deliberately miss the point....
9 February 2019 | by josephlockettSee all my reviews

Y'know, there sure are a lot of malignant "Sons of Liberty" leaving reviews of this episode....

"You, too, are a hero." That's been the ongoing message of this series. And just because a few cranks can't tell a hero from a villain, or think their own hate is more important than others' love, doesn't make that credo any less true.

"I have faith that the love between two sisters will prevail in the end." And so it has, in this show and in this nation's history. The haters will die out, give up, or come over, and we'll keep moving ever closer to truth, justice, and the American way.
