The initial plot set-up for "Starlight Hotel" is virtually identical to that of an American film made two years earlier called "The Journey of Natty Gann". Greer Robson plays young Kate, whose father leaves New Zealand to find work during the Great Depression. After things don't quite work out with being left behind, she decides to find her own way out to meet him. This film isn't quite as well-realized as the aforementioned American production, but it's still an excellent watch for kids. There's two major highlights here - the first is Greer Robson (who I'd liked in "Smash Palace", made six years earlier) who gives a very engaging, natural performance. The second is the vivid and beautiful cinematography by Warrick Attewell.
The major, distracting downside is the music. Instead of making something a little more chronologically appropriate for a film set in the 1930s, Andrew Hagen and Morton Wilson composed a soundtrack full of echoey synths and tickling pop piano. It's rages above the soundtrack like a whore with hideous makeup. It's the only time I've ever heard music that was so bad it came close to sinking an entire film.
There's all the inherent improbabilities one might expect from an adventure story aimed at younger audiences, but it doesn't fly in the face of reality too much. None of the humor is cheap or easy. "Starlight Hotel" is generally a lighthearted film, and by extension, a rather lightweight one as well. I enjoyed a lot. You should too, especially if you watch it with children.
