Slow Boat to Madness Part 2 picks up with Quincy (Jack Klugman) and Dr. Janet Carlyle (Diana Muldaur) still trying to identify and contain the mysterious illness that has now caused three deaths and made others severely sick on the cruise ship. Meanwhile, two passengers who have defected from their country and fear being being caught during the crisis decide to jump ship as it is docked and swim to a nearby island where the hostile government is aware of the health issues on the ship and will not allow anyone to enter. Sam (Robert Ito) and Mark (Marc Scott Taylor) arrive at the scene and locate the ailing couple on the island and then bring them back to the ship where they assist Quincy and Janet in narrowing down the origin of the illnesses. The situation becomes even more dire for Quincy as Janet suddenly falls ill and displays the same symptoms as those infected.
The second part of this episode seemed even more dragged out than the first to me and we pretty much see more of the same with people getting sick throughout. I also found it pretty silly that Sam and Mark were called onto the boat to help with this crisis. Wouldn't there have been experts and specialists from the CDC or NIH flown in to assist rather than two assistant LA coroners?? I won't give anything away, but let's just say the cause of the illnesses ends up being a pretty random thing which seemed very anti-climactic after we heard all of these wild and exotic potential causes over two episodes, so this was a big letdown as well. I further couldn't believe what I was hearing in the scene towards the end where Quincy mentions charges are pending against the purchaser of the item which caused the outbreak, wouldn't the responsibility and any prosecution be on the manufacturer??
All in all, this is a pretty weak and flawed conclusion of a Season 7 two parter which I do not recommend viewing.
