It is total lunacy of course. But who cares? Films are meant to be enjoyed and I often watch films with many guys and girls watching with me. All the girls were crying to this....
The word "alien" sounds terrifying; the director of Starman knows this so he based the alien character around the beloved, dead husband (Scott)of a young woman. She is terrified by the alien to start with, then starts to trust him, and finally loves him. It probably sounds yucky - however, the director stops it being such.
I particularly like the bit where Scott (the alien) tells her that, despite her infertility, she will have a baby and he will make sure the baby will be okay is particularly heartwarming. Another nice bit is where he gives her his final "crystal" at the end of the film. "What will I do with this" she asks. "The baby will know" replies Scott. Wonderful stuff.
This is a very nice film. It is romantic, scientific and, in a way, frightening - in that we as a species are so fearful of unknown phenomena and we greet such with violence. The film plays along this thread and demonstates that Scott is millions of years ahead of us in technology and that we are little minnows against him.
A wonderful movie.
