Wow, you are a lot more forgiving than I am.
Like I said I just starting re-watching them again so I watched season 1-3 like I don't know maybe a year or two ago, but I remember quite a few stinkers.
I don't even remember some of these episode. I have no memory of a ship shrinking episode. Something to look forward too.
I love the series over all but there are some episodes I would cut out like Thomas Jefferson ripping pages out of the Bible.
I can go back and try to recall which ones, but it would be difficult to remember some of them. I tend to block these things out.
