That's the great thing about filmmaking: There's no right or wrong, only tastes. What is good for one filmmaker will be different for another, whether it be plot, script, acting, even color. MCU movies are great to okay in my opinion. But so are some of the Scorsese movies. Raging Bull is great, but I know several people who can't understand why anyone would want to watch a black and white movie about a washed up Italian boxer.
