I've started rewatching them all from the beginning. What I've found is despite the fact that I love the show in almost every episode I find myself wondering what the heck. Examples:

1. Green Green Glow of Home - Clark is chained in the back of the van. He tests no powers. Then it seems like a few second or minutes later and he is back to full strength. Bust the chains, kicks the doors off.

Now if that isn't bad enough. Trask signals the guy off - the driver. To take the van away. He knew Clark Kent was in the back. So how come the world doesn't wind up knowing that he is Superman. I'm sure someone would have bought the story.

2. Smart Kids - Which actually showed before Green Green Glow of Home. The kids figure out he is Superman. He sort of tries to unconvince them. But at the end in chalk they right Clark Kent=Superman maybe? I can't imagine that one of those kids didn't tell someone. So again how come the world doesn't know he is Superman.
