Having cancelled all TV service, now all I can watch is what I have on DVD, so this morning, I decided to watch a Lost In Space episode and grabbed a disk at random. The first result was Space Circus, and what can I say? The episode was very unimpressive.

Space Circus is one thing, but a woman who seems to want to leave and that plot goes no where, but then suddenly, we have to take Will with us, for no reason? Because a machine made him telekinetic?

Overkill on Will, for starters, then the totally strange bit with Smith convincing Will they don't have enough food, so he makes that noble sacrifice.

Now the ringmaster says Will cannot leave with them because his heart was not in his departure.

Total bunk. Just a worthless waste of an episode plot and adventure. Went absolutely nowhere.

Lost In Space is truly an oddity. Find a good episode and it can be enjoyable, but when they are bad, they are truly forgettable. There are others worse than Space Circus, but this certainly wasn't one of the good ones.
