In 1999 during a BBC2 themed evening, "Doctor Who Night" (13 November 1999) hosted by Tom Baker, a special edit of episode 7 "The Rescue" was broadcast which included 5 minutes of footage from episode 6.
Christopher Bahn of The A.V. Club wrote that The Daleks is "quite solid, full of well-paced action and some interestingly subtle characterizations, though it definitely begins to drag around the fifth episode, with a long trek through swamps and caverns that moves the plot forward by about an inch" [REF].
