Every superhero show has two recurring episodes. The one where the hero loses his sight and the one where he loses his memory. Why is that? I think they're just easy plots and writers take advantage of that. For the most part these episodes are fun and I'm not complaining. Just wondering if anyone else has noticed. Here are just a few examples I can think of. The Adventures of Superman one I went looking for. Post some if you have any.
