Personally, I have Breaking Bad on the brain at the moment. This story and the way it's been told have just been so amazing. The show has been crafted with such a high level of precision in virtually every respect. The characters are nothing but three dimensional, the acting is unsurpassed, other shows are trying to copy the writing (story & dialogue) and failing, not to mention the path that the show blazed with the cinematography.
I'm going to very sad, I think, around 7 PM tomorrow night. But I'll never forget how this show demonstrated just what was possible with a true commitment to excellence.
