Ryan McGee of Zap2it described "White Rabbit" as "a worthy successor to 'Walkabout,' and one of the stronger Jack-centric eps the show ever produced." Lost Episode Guide for Others: An Unofficial Anthology by Robert Dougherty says the episode is a must-see; it is "our first in depth glimpse at Jack's character".
The assessment of "White Rabbit" as a standout episode focused on Jack is corroborated by Ryan McGee's favorable appraisal, which places it above another episode ("Walkabout") and emphasizes its importance in revealing Jack's personality.
