Why crash the antenna

Rating: Null/10 (28 December 2015)

I don't know if I should say I liked it or not, however, an interesting Sci-Fi.
Yet, aside the good acting and the idea of using clones to replace astronauts which could have led to a film dealing on economy or savage capitalistic economy even in space, there are things which needed to be developed. For example,when Sam Bells contacts his daughter and she cries out to her father someone is asking questions about her mother, I assume the father is Sam himself, probably the first of the cloned Sam Bells.Seems that years have gone by therefore making Sam Bells on the moon station the third of many. Or, when the last clone, before leaving for earth crashes the lunar jeep on the antenna, why? Considering it is a Sci_Fi movie, I understand that to make this movie a science fiction, the idea of insanity due to a long solitude is better than dealing with space economy and using clones (in our earth's future-robots) which is less threatening as a subject since insanity to long periods of solitude is far from our reality.
