There are two categories of “good movies” in my mind. There’s “good cinema,” which represent an approach to consuming and appreciating movies based on their ability to leverage the medium to convey a story and characters in a way that would be impossible in another medium (such as literature or television or stage play). I don’t really put any time or effort into this sort of appreciation any more.
And then there’s “good flicks” which are movies that are not ‘good cinema’ but are enjoyable and I don’t feel as though I’ve wasted my time. Indiana Jones trilogy is definitely in this category and I still adore the movies. I’ve not kept up with MCU, but I believe those may live firmly in this category… but I am often surprised when seemingly “non-art” (i.e. business) projects come out of Hollywood and flirt with the former category.
