Sambutan kritik adalah amat tinggi. Christian Clemmensen of Filmtracks memberi pengiktirafan penuh iaitu 5 bintang.  Jonathan Broxton of MovieMusicUK juga memberi lima bintang, menyatakan "Harmoniknya yang sentiasa memuaskan hati, pengorkestraannya yang menarik, dan tema hero berkuasanya dapat dinikmati sepenuhnya dari mula sehingga tamat, menjadikannya antara pengalaman muzik yang amat memuaskan hati dari musim panas 2010."  James Southall of Movie-Wave memberinya 4 bintang.  Tom Hoover of ScoreNotes memberi runut pengiktirafan 9.5/10, menyatakan "As far as collaborations go -- this one is the best of the lot between James and M. Night Shyamalan."
Two criticisms have been leveled at the commercial pressing of the album: the fact that the album presentation is lacking "narrative flow", which is "an aspect shattered by a non-chronological presentation of tracks on the commercial album for The Last Airbender", and that of the choir having been reportedly edited out of the release of the album due to re-use fees. Jon Broxton, though, says this: "There has been quite a bit of criticism aimed at Lakeshore Records for apparently not licensing the full choral elements heard in the film for release on CD; having seen the film, I can honestly say that whatever choral elements exist in the film are not especially missed on the CD release, and the final cue – “Flow Like Water” – sounds exactly the same here as it does in the theater."
