As mentioned, the main theme on this disc is definitely one of the best of Horner's career, and it's one that's difficult to get out of your head once you hear it. It is even supplemented by a great secondary theme and a terrific love theme for Jenny, played by Jennifer Connelly. Many have mentioned the main theme's ability to create the illusion of flying through sound, which is extremely noticeable, especially when Horner introduces the sound that is reminiscent of his earlier swirling strings, only this time generally played by woodwinds which sound different yet familiar all at the same time.

Though the entire disc is fun and engaging, it does go slightly downhill after the first two tracks which basically steal the show. Track two in particular is very loud and raucous, causing the listener to become less enthusiastic about the rest of the music on the album, though the final track contains a very exciting conclusion.

As for originality, the music sometimes borrows quite heavily from Horner's earlier two Star Trek scores. The main ostinato from the Trek scores is mutated into a lot of the work and some ascending horn motifs sound very familiar, as does some use of celeste, but it really doesn't reach the point of hurting the listening experience at all. In fact, it sometimes helps to create a nostalgic feeling for those familiar with the composer's early work.

Some don't like the inclusion of the two songs in the disc (tracks 4 & 8), but I actually like them, though I feel that it would've made more sense to put them at the end of the album, as opposed to random locations between the cues. And since the songs are placed in the middle of the CD it would have made me happy to have them labeled as songs instead of score.
