I saw this movie only once, and about a couple of years after it was made. By that time I was seventeen, and needed some counseling very badly...
I can't remember much of the plot, but certainly I can remember my feelings, and it certainly made me think about myself and how with the help of other (older) people I could overcome the emotional growing pains (almost) every teenager is bound to.
Five out of five, just for the sake of being a positive movie, worth remembering thirty years later.
By the way, I just discovered that Peter Boyle is also the extraordinary Frankenstein monster in "Young Frankenstein (1974)"
