Rather childish film for someone used to modern films

Rating: 3/10 (12 May 2012)

The film does not make sense.
The science-fiction part is outdated and even amusing: space suits emitting CO2, funny computer monitors and keyboards, etc.
Since the film was made in 1979, these technical details are forgivable.
The idea of having a crew mainly made of humans is absurd, given that they obviously are capable of making really advanced robots.
Not for a second I was surprised by the plot of the film.
I can understand why this film was a top film in 1979. But I can't see why it should deserve any score above 6 in the 21st century.
