So the moral of the story is: I like it more than Steph, we're both glad that we saw it, and we were intrigued enough to watch most of it just now for a second time. I'm still not exactly sure how I feel toward it, and it definitely didn't blow me away in the same way it seems like it blew some others, but like I said, I'm definitely glad I saw it and the music is great.
A couple overly-specific points that you probably won't care about, especially if you haven't seen it yet:
1. What a great musical end to the movie, returning to the first song that Guy and Girl originally sang together, but as she looks out the window it swells into a slightly different arrangement with gorgeous strings! Great!
2. The soundtrack that Dave loaned me has a couple secret tracks that are remakes of Van Morrison tunes- AWESOME!
3. Did anyone else think it was fishy how quickly Girl caught on to the structure and melody of the song that she and Guy first sang together? I know I'm not the single greatest musician or singer in the whole world, but I feel like I understand enough to say that you can't perfectly guess every note of a melody well enough to nail your harmony the first time you try it. And there are some weird pauses in between parts of the song that she guesses perfectly, that I wouldn't have understood myself without some explanation.
4. One other critical point: Feel free to make a movie with a way excessive amount of music in it, so that maybe it even sort of feels like you're watching a long music video punctuated with brief bits of dialogue. (Especially if the music's so good.) And feel free to include entried songs when maybe it would be okay to edit some of them down a little. But please don't show me a band recording an entire song in the studio, followed by a musical montage of the band riding in a car and playing frisbee on the beach, with the same exact song playing again over the montage. Maybe I'm being too critical, but it seemed like a weird decision, especially since I was a little taken aback at the amount of overall music.
