I managed to binge watch this show all in one sitting. Most of the characters are obnoxious at the beginning, but they all start to grow on you.
Each episode is centred around a particular crisis the ship faces. Episode 8 is probably one of the most darkly hilarious things I've seen on TV.
The show is particularity relevant with all the real-life cruise line debacles that happen of late due to the coronavirus visitor bans happening all over the world.
