When a bad memory is good.

Re-watching great shows, is an excellent example of when you don't want to remember everything. Knowing just the basic plot, and not the specif details to a great show you have seen really makes it a lot better the second time. That way you still get the excitement while watching.

So I only re-watch shows sparingly, like once every two years. This is the only time I would prefer to not have a better memory, and many hours of entertainment have been gained from that lack of memory. So drink up and forget the details of your favorite shows!
