Synopsis

Set in a war-torn reimagining of 1914, Leviathan follows Alek, a fugitive prince of the Austro-Hungarian Empire, and Deryn Sharp, a daring young girl disguised as a boy to serve in the British Air Service. When fate throws them together aboard the HMS Leviathan, a massive, living airship made from genetically engineered creatures, they embark on a world-changing adventure that will challenge everything they know about war, loyalty, and identity.

In 2009, American writer Scott Westerfeld wrote the first book of the trilogy of the same name, entitled Leviathan, which takes place in an alternate version of World War I.

Now I don't want to write a super detailed review on this, but it handles like a typical modern Disney film, with the typical lesbian involved, the simple lessons learned, and previously stated, wasted potential. I mean for one, take the Sultan shown around episode 6, when Mr. Sharp first meets him, he's hyped up to be a main antagonist, with ...
