The opening sequence of this episode was rather neat, the way they indicated the vastness of the artificial planet.

I didn't really care for the way that Venus brushed off Professor Matic's devotion to the pursuit of knowledge. There is always more to learn.

Given that they had had a total eclipse of the sun, shouldn't it have been darker down at Space City?

Is it a television law that little aliens have to have squeaky little voices?

Steve's weapon might have been deactivated, but why didn't he just pick up one of those little guys and heave him at the wall? They didn't have anything to lose at that point.

It was nice that Robert had a chance to shine, and I liked the irony that no one would remember what he had done. However, it seems too much of a coincidence that, in this episode where he was so needed, he was not left behind in the main body of Fireball XL5. What was their reason for bringing him?

And I don't suppose that it will occur to anyone to ask Robert to report what happened. Venus tried to pass it off as a hallucination, but this wouldn't explain why a sizeable portion of the Earth's population witnessed a total solar eclipse.
