West if Mars is pure fantasy. And a giant mess.
I give it two stars because we get to see Jonathan Harris play Zeno, the outlaw. And we get to see Jonathan Harris play Dr. Smith. AND we get to see Jonathan Harris play Dr. Smith pretending to be Zeno!!! And Allan Mervin (Barney Hefner from All in The Family) in the Space Enforcer.
Otherwise, this is a "1". Watch only if you want to view every episode.
Most of the scenes are way over the top, such riding away on giant stuffed animals. If some of the super campy scenes were eliminated, this could have been decent. The fact that the Robinsons can't tell the difference between Zeno and Dr. Smith really compounds the huge gaps in this episode.
Dr. Smith (as Zeno) does have some funny lines, but nothing can save this mess.
