Ratings

Critical response

In a review of the first nine episodes, Hidden Remote critic Georgia Makitalo gave the second season a letter grade of a B, noting that it's "more for the bigger story that I believe the writers are setting up for viewers," and that the grade could drop to a D if the storylines do not improve soon. Praise was given to the stunning and campy scenes that "make the show worth watching," such as The Great Gatsby inspired party and the Wizard of Oz dream sequence. Criticism was geared toward the lack of direction since selling Carrington Atlantic, noting that "Fallon needs something to do," as well as the Colbys' lack of screentime.

Makitalo was also disappointed in Alexis's development in the second season, stating:

Elizabeth Gillies is the clear star of the reboot, although it appears that the producers believe it is Nicollette Sheridan. While the former Desperate Housewives star brings a lot of gravitas and camp to the CW show, the writers have failed her as well. Alexis clearly has a back story that they have failed to uncover. Thus, Alexis is hardly sympathetic, and they are wasting Sheridan's exceptional talents.^[78]
