Just a tiny thing that occurred to me while posting on the thread about the scenes that you love.
HiM is one of my favorite episodes but also has one moment that makes me go "Hum?".

When Lois is running away from the pier there's a door and somebody in editing must've made a strange job with the technology of the time because you can very clearly see that the image inside the door and the background aren't the same.
