Here we get a proper review, the kind that gets somewhat rare nowadays (certainly Jonathan didn't indulge readers with one). Here's just one graf:

The most fascinating part of the series is probably the more realistic approach to the creative process. While there are certainly dramatic liberties taken with the creation of art I do feel the whole process around making something creative comes off a more genuine in Barakamon. There is much more of a look at the trial and error of making a piece of art. We see Seishuu failures, aborted ideas, test runs, and good ideas that don’t pan out even more than his completed works. His works are 90% blood, sweat, and tears and 10% amazing inspiration. There is a little bit of fantastic realism but overall it at least feels authentic and that is what is most important.
