According to the
Nielsen Media Research, "Do-Over" was watched by 8.7 million households in its original American broadcast, and became the highest-rated episode of the series, until the December 11, 2008, episode of
30 Rock "
Christmas Special". It earned a 4.1 rating/10 share in the 18–49 demographic.
IGN contributor Robert Canning reviewed the episode, saying it "[set] the bar for the rest of the season" and was "filled to capacity with comedy." Jeremy Medina of
Paste magazine commented that "Do-Over" was "sort of like the first day of school after summer vacation: sort of awkward at times, but fast and buoyant and warmly familiar all the same."
Bob Sassone of
AOL's
TV Squad wrote "...this episode manages to do what the show has always done, mix crazy, almost surreal humor with a genuine (not manufactured) heart."
TV Guide contributor Matt Mitovich enjoyed "Do-Over", and enjoyed Jack's story of trying to reclaim his job, along with Jack and Liz pretending to be a couple in front of Kathy.
The A.V. Club's Nathan Rabin opined that premiere episodes "tend to be
30 Rock's Achilles Heel. But the show comes roaring out of the gate with 'Do-Over', a show that definitively breaks the premiere jinx." He said that the "frenetic farcical plotting" of Megan Mullally's character—in which she endured a disastrous trip to the 30 Rock studios, bumped her head, and lost her memory—"felt a little sitcommy but the laughs kept coming". In conclusion, Rabin gave this episode an A− grade rating. Television columnist Alan Sepinwall for
The Star-Ledger felt that the element's towards Jack getting his old job back were "fairly labored", but noted that Liz's adoption plot was "more solid from start to finish". He was complimentary towards the Kathy Geiss character, observing that her actions in the episode were "all frighteningly funny", and enjoyed Mullally's guest spot. In conclusion, Sepinwall said that this was not the best from the
30 Rock staff, but "they had some things they felt obligated to deal with, and there was more than enough comedy genius that I can't really complain." ==References==
