Defined by the onset of gripping serialized drama, a growing interest in more mature and confronting material, and the perfection of the writing and performances, the best series of the decade made an immediate impact with their ceaseless excellence.
It is also impossible to deny that the ability of so many great shows of the era to deliver rewarding finales has played a huge part in making them such enduring highlights of the form, solidifying them as series fans can revisit multiple times without dreading a dismal ending. Ranging from groundbreaking crime dramas to dark comedy dramas, winding sci-fi spectacles, and even an animated sensation, these series delivered some of the best series finales of all time.
