That depends entirely on what each person finds entertaining, and even then I bet there’s a bunch of people that would argue that some of those top 100 movies aren’t entertainment but culture.
Nothing wrong with not liking a movie or show even before watching it but I would recommend to give them a chance from time to time just in case, you never know. This is something I miss from old linear TV, to have stuff already on that you started watching out of boredom because there wasn’t anything good on and then realising that it was more interesting than expected.

To find those movies or shows boring it’s not being picky. For me picky would be for example to only watch movies if certain people are in it.
