[Zzzzzzzzzzzzzzzzzzzz]

WARNING: ONLY READ IF YOU HAVE SEEN THE FILM BATMAN VS SUPERMAN! OTHERWISE IT COULD SPOIL YOU!!!

































Hello there.

I have not seen Batman VS Superman the film yet. I was watching a YouTube video that was completely unrelated to the film, I look in the YouTube comments and somebody says "Superman sacrifices himself to Doomsday with Batman's kryptonite spear" . IS THIS TRUE?!? HAVE THEY SPOILED IT FOR ME?!? If so, how do I deal?

Thank you very much, help is appreciated.
