Bosch: Legacy is being ushered out the door at Amazon, after over a decade of highly successful Harry Bosch crime stories. It isn't the only long-running ratings hit to be canceled this year, after CBS ditched Blue Bloods after 14 seasons. The difference between Blue Bloods and Bosch: Legacy is that, unlike Amazon, CBS did agree to at least give the show a proper ending, rather than end it abruptly.
