No. You are wrong. Not everyone thinks that way. I decide if I want to spoil information about a movie/game etc. or not. Example: I still haven't watch Star Wars 7. I'm waiting for all 3 films to be complete. Then buy the boxset. Guess what: I decided I didn't care if I read some spoilers. I know Han dies, and why. Still buying the movies, once all 3 are done.
Congratulations, I guess.
Seriously though, I never said everyone thinks that way. I said your overall experience diminishes if you know all the spoilers. To say that is not true is a lie. I do not believe you..
If i knew Han Solo was going to die before I watch the movie I won't be shocked and surprised when it happens no matter how many times I rewatch it.
