To address the OP..
While our eyes have a limited depth of field, most people are not aware of it because we focus on whatever we are looking at it.

Part of creating eye-catching photos is presenting something not often seen.
Using a narrow depth of field is an artistic tool that allows one to do just that.

In addition, using narrow dof / large apertures allow the photogrpher freedom from some common problems. Namely distracting backgrounds and blur caused by camera shake.

However narrow dof introduces one shortfall to photos. You can only see one thing. There is no option to scan the frame and see what is going on behind or in front of the subject. Once you have seen the main subject, you may as well turn the page and go on to the next image.

So if you like narrow dof, then by all means use it. But get really good at it, or only use it when you need it.
Don't use it as a fixall.
