So why do previews exist? Well, there are actually quite a few reasons. For one, previews can generate interest in whatever it is that’s being previewed.

They can also help people make informed decisions about whether or not they want to see or purchase the full product. Additionally, previews can serve as an introduction to something new and unknown, helping people become more familiar with it before diving in headfirst. Ultimately, though, it’s up to each individual to decide whether or not they want to watch or read a particular preview.

Some people love them and can’t get enough; others find them annoying and prefer to go into things completely blind. There isn’t necessarily right or wrong answer – it all comes down to personal preference.
