Critical reception
Critical reception to the first episode of the series was mixed, with positive reviews from The Daily Telegraph, The Herald, The Spectator, and the New Statesman, and negative reviews from The Times, The Sunday Times, Newsnight Review, The Guardian, and The Observer, which criticised the episode's direction, structure, and tone (although it did praise the costumes and art direction). The national free sheet, Metro, gave the episode four out of five as "a vote of faith" on what it described as "a dodgy start".
The Guardian reported on 15 February 2008 that, with 6.1 million viewers and a 25% audience share, the ratings for the second episode, shown on 14 February, were down by almost one million on the first, comparing overnight returns. It still did well against the Lynda La Plante police procedural Trial & Retribution, which fell to a series low on ITV. The fifth episode, broadcast 6 March 2008, attracted 6.6 million viewers according to overnight returns. With this episode, The Daily Telegraph stated that "Ashes to Ashes stepped out of the shadow of Life on Mars".
Hawes's performance was singled out by critics such as The Sun's Ally Ross, The Daily Mirror's Jim Shelley and The Guardian's Sam Wollaston. While Robert Maclaughlin, writing for Den of Geek, praised Hawes for "the ability to pull off a white leather coat, perm and very, very tight jeans", other critics were negative; Ross blamed the character of Alex Drake for "ruining nearly every scene". Wollaston went further, writing "Keeley Hawes, as DI Alex Drake, is awful. She may be totally shagworthy and have a cracking pair of puppies (those are one of Hunt's sidekick's words, not mine, before you start complaining), but, as a copper, even a psychologist copper, she's very unconvincing." Philip Glenister defended his co-star, stating, "It's a hellishly difficult thing to come into and I've seen how hard she works and how brilliant she is. To all those detractors, they're just plain wrong." Hawes sent all her critics flowers.
Entertainment news website Digital Spy praised the show's return, with cult editor Ben Rawson-Jones describing the opening episode of the second series as "greatly promising". It was watched by 7.01 million viewers.
The second series was nominated for the TV Dagger at the 2009 Crime Thriller Awards. Keeley Hawes and Philip Glenister received nominations in the Best Actress and Best Actor categories respectively.
The finale of Ashes To Ashes, which finished in 2010, has been described by Dean Andrews as "genius". He explained on GMTV: "Everything is tied up. You get all of the answers from Life on Mars and Ashes To Ashes."
When interviewed by SFX Magazine in May 2010, Matthew Graham spoke of teasing the BBC with a third set of series called The Laughing Gnome (the title, an early song by David Bowie, suggests a prequel set in the 1960s), and claimed that they made "the whole title page and copyrighted it and everything". He said the BBC responded well to the joke, replying "Yeah, it's commissioned!".
The series three finale was watched by 6.45 million viewers.
Sam Wollaston called the series a nostalgia fest. Other journalists also commented on nostalgia in the series.
