Critic Reviews for O Brother, Where Art Thou?

[Jon] Cryer's Lex in conjunction with McGrath's Lena provide the backbone for a very solid episode of Supergirl.

I don't remember the last time I enjoyed a Supergirl episode this much. At least not this season.

It's been a tough week for our friends in National City, but it made for a great episode of television, and I hope it will help Supergirl power through for the rest of the season.

'O Brother, Where Art Thou' was a success on all fronts, introducing Lex Luthor in a way that remained relevant to the show while using the urgency of the current events to move the story forward in a major way.

It's perfection, and the only thing that made it better was the trailer for next week.

After a season built on slow and steady worldbuilding, "O Brother, Where Art Thou?" doesn't just rearrange the board, it seems to rewrite it entirely.

As sad as I am to see the (apparent) end of the Elite, I'm all about this new triumvirate of evil.
