CMV: Marvel movies would better better for the viewer if they didn't reveal major plot points in the trailer

Example 1 Captain America: Civil War; if they didn't show Spider-Man and Black Panther in the trailer the movie would have been better because you let the viewer be surprised that these characters are actually in the movie.

Example 2 Thor: Ragnarok; When you saw the Thor Ragnarok trailer or even first heard that Hulk was going to be in the movie what was your reaction to it? I am guessing you were surprised, amazed, excited right? Imagine seeing them first showing up on the big screen. 

By showing the characters in the trailer they unintentionally make it so these emotions you are supposed to be feeling in the movie are dulled.

I find it odd that you think they are "unintentionally" dulling the surprise of the movie. They're doing it on purpose, because it makes *the trailers* more interesting, and generates hype for the movie beforehand.

Take Thor: Ragnarok. When the trailer dropped and Hulk was shown in it, people went *nuts*. Along with the bright color scheme and tone shift, the Hulk reveal generated a massive amount of buzz for the movie and got people excited for the movie, leading to more people going into the movie and the people going into the movie *anticipating* Hulk and being entertained waiting for him.

Is that an objectively "better" experience than being surprised in the theater? Depends on the person, because hype leading into the movie is part of the experience for a lot of people. Some people might not like it, while other people might love having some of the "reveals" show up early to keep their hype levels up. And it certainly means more people show up to the movies, which is a pretty important metric.
