Paradox

BBC I truly love you and I adore your series, so tell me please- why did you stop producing this one? I've read critical opinions about clumsy dialogs, bad acting, non-logical storyline, but every movie/series have them and they're going still. So why that, in my opinion, interesting, intelligent, fascinating show had to end? And had to end in such a moment? Personal I've found dialogs, acting very good. If storyline wasn't absolutely logical, I've hadn't notice that. Maybe it wasn't most important, maybe I just wanna be lied- it's a show- it can lie, because it's its own magic Is there any chance to back to production? Sadly, I know the answer.
