series will be so much more so without her." Stephen Brook of The Guardian commented that "the departure of the much-loved Rose ... was brilliantly handled and completely unexpected." Stephen James Walker, a writer of reference works on Doctor Who, gave an unfavourable review to Rose's return in "Turn Left" in his "unauthorised guide to Doctor Who'''s fourth series," Monsters Within. He thought that Billie Piper was "distinctly below par", citing her gaunt and malnourished appearance, new hairstyle, and slight lisp as reasons why her acting was not her finest. He criticised her role in the episode, stating it had been "far less well worked out" than Donna's. Ben Rawson-Jones of Digital Spy also noted a change in Piper's enunciation; he compared her accent to "[having] her mouth numbed with local anaesthetic". In Rawson-Jones' review of the series finale he notes that whilst having the Doctor and Rose 'cop off' would be divisive with the shows audience, "Davies wisely managed to please both parties" by pairing her off with a human Doctor instead. However, IGN's Travis Fickett reacted unfavourably towards Rose's return and her pairing with the part human Doctor. He thought that it undermined her "perfect send off" in "Doomsday" as she was on the sidelines for much of "Journey's End", and her ending up with the part human, part Time Lord Doctor "feels like an insult to the character". Io9's Charlie Jane Anders also reacted unfavorably to Rose returning and wrote "it was pretty clear that she was only there so she could get her pet faux-Doctor at the end." Reviewers generally reacted positively to Piper's 2013 appearance in 50th anniversary episode "The Day of the Doctor". Ben Lawrence of The Daily Telegraph called her performance as the "Bad Wolf" Rose "transfixing". Neela Debnath of The Independent praised the chemistry between Hurt and Piper and compared Piper's performance to Suranne Jones' portrayal of the TARDIS in "The Doctor's Wife" describing it as "slightly eccentric", "oddball" and "off-the-wall". Daniel Martin of The Guardian praised Steven Moffat's decision not to extend Rose Tyler's story or re-unite her with the Tenth Doctor. He called Piper "a true and unending legend of Doctor Who" and stated that "her wise rendition of the Bad Wolf avatar made a passable stab at the stealing of the show". Geoff Boucher of the Los Angeles Times named Rose the ninth best sidekick of all time, referring
