Critic Reviews for Dark Waters

Damien Darhk is pretty much the perfect Arrow villain... [Neal McDonough] makes it clear how much Darhk himself relishes the theatricality of his villainy.

On the surface, there are a lot of exciting elements, but those bright moments only temporarily distract from an otherwise rushed and clumsy episode.

A heartbreaking cliffhanger.

Finally gave Olicity fans what they've been begging for ever since Felicity was introduced on the show, only to then devastate the fandom in the final shot of the episode. We're talking real devastation, people.

I have to admit, intercutting the attack with scenes of Damian Darhk going home to his adoring family and placing a star on the tree? Very nice.

A tense episode and one of the season's best, but with a very cruel cliffhanger.

Damien Darhk's master plan came to light... and it was disturbing as hell.

There was a lot to like about this midseason finale. It was really well paced, and although it was pretty dramatic and dark, it also managed to be festive and cheerful.

Even though you saw the proposal and the attempted murder scene coming a mile away, it was still pretty shocking in its execution.

What would have been an otherwise trite kidnapping subplot was saved by two things: Olicity and Malcolm Merlyn.

Aug 1, 2018 | Rating: 4.5/5 | Full Review…

"Dark Waters" may have been guilty of playing around with the audience's expectations, teasing a number of possible victims, but it also made sure to showcase Oliver and Felicity's relationship and to demonstrate why it has worked so far this season.

It really can't be overstated how great it felt to have an Arrow episode that actually functioned as an Arrow episode again, and "Dark Waters" mostly knocked it out of the park all the same.
