Sure, this series ended with a talking carrot but it was "the" show to watch in it's time.
The original B+W shows were great before Dr. Smith turned totally gay and wimpy and the robot "got nice". This show had REAL models that looked cool and the wire work on the model was some of the best of it's time.
Who can forget the first crash landing of the Jupiter 2? With is screaming over the mountain tops...No friggin CG effects!!
Great cast. The show did have some cheesy monsters and some really dumb stories but it was a great show no matter how you look at it.
