Lottery Episode Emblematic of why this was cancelled

I've been watching this series episode after episode, having bought the DVD series.

It was pretty good for most of the way, but by this episode it was clear that humor and whimsy are no substitute for plot. Let me explain.

Early on, the series established a few things, among which were the following:

1) Our hero who traveled back in time could not create a paradox by doing something that would change what was reality that had always been fact, and

2) He could not bring something back from the past, like a piece of paper (like a lottery ticket--which would have become erased).

Ok. So now the Lottery Episode. Out hero says that he can avoid all problems by not buying the ticket himself, but telling Holly (or, at the end, someone else.

This violates #1.

The only way this *could* have been done correctly would have been if he had not known if he had won at the time he decided to go back. Because then it would not have violated what was fixed.
