I find it rather cheesy to be honest, either on its own or as a coda. I much prefer Horner's orchestral treatment in the main body of the score, one of my favorites of his. I guess I confess that I do still like the song, but only because I like the thematic material it's based upon.
What I would LOVE is for there to be an expanded release of this score. There's a good 12-15 minute unreleased, with some real highlights among it.
