I know we have a few fans of this terrific show. Don't get your hopes up just yet of it returning soon, but it is returning for the 4th and final season.
Seems there are going to be several new characters added and others who just made appearances, will get regular reoccurring roles.

If you haven't become an Ozark fan, and you like GREAT TV, with lots of action, killings, and never know what might happen next, this IS the 'it' series for you. Just great TV, great acting, writing, and excitement that builds all thru out the series.
