for the first forty minute or so and luna be a real pleasure to watch . the character and their situation be interest and the photography and location be beautiful to look at . then jill clayburgh discover her son matthew barry be use heroin and the movie start to unravel and then becomes outright laughable in it sickness . clayburgh ask him why and when he start use the drug and she nor the audience ever get a straight answer and which would be a bit helpful . he mention not care about anything but that not right because we see clearly in the amazing early scene that he have a good deal of interest in his mother singing and baseball and sex and and apparently care enough to turn down marijuana . this movie be for people who think junior get into hard drug because mom and dad be workaholic who miss his piano recital . i think such a dangerous and emotionally volatile drug like heroin be choose a some sort of intellectual catalyst for the late scene of incest . there a lot of discussion about the mother love for the son but it really about bernardo bertolucci be pretentious . luna would have be great a a quaint little family drama . how old be matthew barry in this movie . i be more concerned over the bizarre thing he have to do a an actor for this film than for anything his character be go through . out of .
