Composer James Horner teams up with director James Cameron again, now for the soundtrack of the blockbuster "Avatar." Back in 1997, Horner worked with Cameron on "Titanic", for whose music he received many awards, especially for its main theme, 'My Heart Will Go On', sung by Celine Dion.

Of his work for "Avatar," Horner says that he has never toiled on such a complex soundtrack before. His approach has been to mix the sound of indigenous instruments from several countries with a few invented by himself. He has also composed the film's main theme 'I See You,' sung with passion by British diva Leona Lewis (audible in the nuances of her voice), who has one of the most beautiful and crystalline voices that have appeared in the British pop scene in the last few years.

Unfortunately, 'I See You' follows in the same musical steps as 'My Heart Will Go On,' to the point that the first two notes of the chorus of both songs are the same (feature the same interval). This lessens the freshness of the song, which could have opted for a more original approach taking advantage of the innovation that characterizes the film elsewhere as well as its exotic location (not necessarily the ethnic-flavored New Age retread that characterizes the film's score).

We can only offer a few educated guesses as to why such a conservative decision was made: the desire not to deviate much from the formula that had brought success before; the fact that the producers of 'I See You' are the same ones behind 'My Heart Will Go On' (James Horner and Simon Franglen); that James Cameron wanted it that way or, simply, lack of new ideas.

In any case, the video itself is worth watching, even if only to enjoy Lewis' beautiful voice while taking in the lush CGI images of the film, which, ultimately, are its main attraction and value.
