I really wanted to give this a better rating. Personally I loved the characters and the cast this season. However the story/writing quality starts going down hill around the mid-way point and towards the end there are so many plot holes and direction changes that even the sincerest of fans will lose hope. If you count the movies as canon as well, which in generally the idea, it gets even more confusing and convoluted.
Overall the cast are wonderful and the story is good at the beginning but the writers clearly lost their thread towards the middle and didn't really manage to pick them up again, ended up with many more questions than answers and an unsatisfying ending.
