The Space Circus: My Favourite Circus
28 May 2007 | by StuOzSee all my reviews

On Planet X, a space circus appears and wants to take Will Robinson away because the circus folk think Will has a special power.

This is yet another LIS episode that was a 1970s childhood favourite of mine but does not hold the same appeal now that I am grown up. For example, in childhood, those early scenes of the big white ape giving Dr Smith a scare were almost mild horror. But I still like the way it presents the circus, in fact, if someone were to ask me what was the most memorable circus seen in a movie/TV episode...I would say this Space Circus. Also good is the atmosphere created by a sometimes touching music score, the odd good line - "We will not leave this planet without that boy" - is good, and solid direction.

However, we have the odd problem area, mainly The Robot's singing/Dr Smith's singing.

Today, this hour can simply be called okay.
