Critic Reviews for Underneath

Now that the Russia flashbacks seem to be concluded, I'm happy that that free time can be dedicated towards other storylines.

Underneath was an exciting episode that had a lot of good one-liners and some decent character development. There were a lot of eye-roll moments, but it was still good to see a different set-up for the series.

This is what we needed... I'm... feeling like I recognize the characters I'm watching. I'm talking about common sense. I'm talking about continuity.

Last week's episode... completely devoid of the story's main villain and lacked the trademark action... It turns out that I should have saved that complaint for "Underneath," which featured even fewer of those key elements.

Underneath strikes just the right balance between taut, self-contained thriller and character piece.

Underneath works because it allows the writers to plumb the depths of a relationship they have clearly been interested in exploring.

ARROW keeps the emotional stakes high while finally acknowledging the relationship elephants in the room.

Hopefully, things get back on track next week as this was a huge disappointment in an otherwise amazing season.
