I'm, like many others too, not happy with the fast ending, but I take it how it is. It didn't destroy my dreams, it didn't changed my life, and it was just a series for me that didn't make up my life. A good core was told and that's it.
Wise words my friend, I agree with you.
You have some good points here, nice review.
As about books matching movies or TV series, they never do.
