This was indeed a very sad ending for a series that has, for the most part, been great. Alaska is a huge place that I knew nothing about until I started watching this show. I can't believe that things were ended this way. The series really needs to be picked up by someone and concluded properly.
The ending with Patrick and Annie was awful and not much better for Marin and Jack. Even though I know the writers had little choice, I really feel that this episode could have rounded things off in a much more satisfactory manner.
Here's hoping that somehow the story could be wrapped up in some sort of Special.
