Yeah, I hate that shit and it reminds me of the Game of Thrones thread where Cezero would talk about the book and then play innocent, not realizing some of us are smart and pick up the details and it ruined the experience.
Even if you drop what you think is an innocuous comment, realize a lot of us are intelligent and what happens is it hinders our viewing. I don't really come too much anymore, as my postings show, but I hated how some people gave reviews and basically wrote the whole movie or important parts out and ruined it. Give your fucking opinion about how you felt about a show or movie, but getting into the specifics ruins it for most of us. That's even why I changed the title of the thread.
