It's not that Mockingjay is a bad conclusion to the trilogy, it is just that what happens in it could have been covered in a book half the size. The rest of the book is filled with hair pulling indecision, angst, and PTSD. Suzanne Collins is good at writing action, so it is a pity that the action is primarily reserved for the last fifth the book.
This got me thinking about when was the last time I read a final book in a series that I liked. Though I liked the Harry Potter series, I didn't think the last book in it was particularly good. (I kind of hate the cop out of the 20 years in the future epilogue, it tells the reader how everyone ends up, but robs the reader of experiencing the wrapping up of all the emotional subplots) Really the only time I can think of being fully satisfied with an ending is reading the Lord of the Rings.
So, when was the last time you reached the final book in a series that left you feeling satisfied? (You still may have wanted to read more, but as far as you saw every question you had was answered and every character had a farewell.)
I need to know this, I'm running out of reading material.
