Nope - not overrated. In portraiture the OOF area takes up - what, 2/3rds of the print most often? There is most definitely "good" bokeh that looks like a watercolor wash and adds to the image, and "bad" bokeh that looks "nervous' and like a drunk person seeing double, which detracts from the image. "Bokeh" is not an overrated quality in a portrait lens - it's way more important than sharpness and is right up there with color rendition. Casual viewers of your photo will know it's special based on good "bokeh" way more so than resolution or sharpness. Also, bokeh is an optical quality that's difficult to add at all in post, and never looks quite as good as natural optical bokeh even when it's well done. It adds a diminesional quality and causes pics to "pop". Color, bokeh - underrrated. Sharpness, resolution, mild vignetting, performance wide open, various chromatic aberations - all vastly overrated especially since many of these can be corrected in post, trivially, now. Flare control is also important.
