Finished the film just now. It does get better in the second half, i.e. after one hour (!). It has its moments, some subtle comedy going on at times, but overall I don't think it's a good movie. The idea and message are good, but the production feels very low budget.
Curious how they have adapted this to work as a musical.
As for Mark's soundtrack, the melodies are gorgeous of course, but the production feels very dated now, and they way the music was used in the movie, it felt a bit obtrusive.
I think a remake, with better writing (dialog) and direction, could make it a lot better.
By the way, Ben, the old man on the beach, reminds me of David Knopfler.
