I never understood those who stop reading a book/watching a movie after they learn what it will end...I think it’s just a scam, because they’re not very interesting to them. I have a few desktop books that I know from the crust to the crust, and one hell I re-read from time to time because the trends are interesting. And some successful films. I know them from time to time, but I still review them from time to time.
P.S It is not recommended to watch historical films :)
