Merely pleasant for most of its run time, but by the time we get to the opera house (and its foreshadowing of A Night at the Opera hijinks) I was chuckling consistently. Not sure that the musical aspect added much. Genius premise that I'm sure has been used elsewhere.

And about time, too.

What an amazing film. Keeps jumping between moods and genres in a way that reminds me of modern South Korean cinema. Also, the amount of room each scene had to breathe was unusual. Most shots have an extra second or two at the beginning or end that gives the movie as a whole a kind of shaggy suspense.
