A question to peolple who feels they've been spoiled:
You just know now Thanos is in this movie, and you know MCU movies are about Superheroes VS Villian(s).
You know this movie is called Guardians of the Galaxy.
And you now know Thanos is THIS movie's villian.
Now, you had just found out the name of this movie's villian. How does that spoil you?
1. Is it because the name "Thanos" brings in something you know about from the Comics or elsewhere?
2. What does the "Guardians of the Galaxy" name means to you? Do you know which are the Superheroes and Villians associated with that name?
You see, this seems like a paradox to me.
If you know who are the heroes and villians of "Guardians of the Galaxy", you should have surely known about Thanos upon seeing the name of this movie?
If you do not know who are the Guardians of the Galaxy and you are not familiar with Thanos, you have no reason to feel spoiled because all you know is this guy, Thanos, is going to be a Villian, unless you are shocked at finding out Marvel movies have Villians!
If you do not know about Guardians of the Galaxy, but you know about Thanos, are you feeling spoiled because you KNOW something about Thanos due to having read the comics and games? Well that makes the most sense since you just brought in something you had already known about Thanos and associated it with this movie, and you think you know the general plot of this movie. Well good thing is, the MCU movies are not that simplistic and generally have twists around.
