Hung Hung movies

I saw a boxed set of Hung Hung movies at Eslite for 1082 NT$. It contains three movies, according to the IMDB, the only ones he’s ever made (he’s basically a theatre director):

The Love of three Oranges, Human Comedy and A Garden in the sky

About the only information I could find on Hung Hung (have to admit that I didn’t look for very long) were a Culture Express and an old Taipei Times article.

Has anybody seen the movies? Are they worth it?
