This show is worth revisiting. I stopped watching it during this season, because it was getting a little too on the nose with what was happening in the USA and the rest of the world. I just couldn't. But I'm glad I decided to revisit my decision. Day 4 has a lot to commend it. For one thing, except for the fact that torture always seems to lead to the truth on this show, the moral problems with it don't just get brushed off. At the same time, there's no pandering or handwringing over it, either. It's very nuanced, especially for a show that is telling a multiplot action story set within a 24 hour time period.
For another thing, there are a lot of women in this show, and they have agency and points of view and important jobs. The one thing that I thought was kind of a drag about this season was the [SPOILER WARNING scroll down past the end of the review to see the drag part]* but even that wasn't too bad.
Alberta Watson and Lana Parilla are two of my all time favorites. As Driscoll and Sarah, they are flawed and competent and very believable. Mary Lynn Rajskub - I think - plays Chloe to perfection. She's hard to take sometimes, but I think it's because she's neurodiverse and a little too smart. Kim Raver is good, but I like her better in a more morally ambiguous role (see, e.g., Revolution). She's fine here, though.
The plot is a bit hit and miss, but it stays plenty exciting, maybe a little more so even than Season 1. And there are plenty of surprises along the way.
