That Ending

This started as a nice, easy going and light- hearted series but I am in shock with how bad the ending was. I was enjoying the story leading up to the last few episodes, that is where is all fell apart. I would love to know what the writers were thinking?? I think they may have been going for shock factor but they did not execute it well in the slightest. They also left many unanswered questions, not questions that are season 2 worthy, just bad writing. It is unfortunate they did that because it was a sweet story.
