SPOILER WARNING for THE 100.
The Ark really shouldn't qualify as a spaceship in that it's actually a space station just as its name suggests, a life-sustaining ark, but it is an impressive creation and of impressive enough design in the series The 100 (2014-present) it's worth covering here.
Unfortunately, little actual coverage has been given to The 100 here at Musings Of A Sci-Fi Fanatic. Though a single post has been in the works.
Nevertheless, Season One and Season Two of The 100 come highly recommended. My enthusiasm for the series waned with the rather redundant and less focused Season Three.
For those interested in a little space in their science fiction though Season One featuring The Ark is the one to see. Additionally, events in that season propel The Ark in a fashion normally associated with spaceships.
