The opening statement of the love theme when we first see Pandora again for the first time in the film is absolutely glorious but it's not on the album. I would have loved that performance to be included.
Also, when Jake Sully and others attacks those ships in the last act, there is a really goosebumps inducing brass performance in the film that should be in the 'Na'vi Attack' cue but it isn't. I also wish that was included on the album.
The more I listen to this score, the more I love it. I still think Horner's original is better but damn it I should have waited a little longer to post my Top 10 scores. This is probably my favorite of the year now.
