Its a very unpopular raid, and Bungie is married to it as the main PVE endgame for the next year. Its one of the major problems facing D2.

the fact that the leviathan is a planet eating ship and could have endless survivors in chunks of unprocessed planets or escaped inhabitants that we have never yet seen lurking in the ships hull do pigeon hole where they can go with the content leviathan is a destination not only with many doors it has more depth than our feeble minds can fathom

Its more like a weird japanese gameshow where I chase dogs with flowers, avoid sumo wrestlers in a bathhouse and jump through a giant tic tac toe maze while running in circles. It's a shame the experience doesn't match the lore. I went from feeling I was fighting awesome, evil bosses in pretty much every other raid destiny has produced to a bad episode of benny hill.
