-- Watching movies? Waste of time
-- Playing Video Games - Rotting your brain
-- Watching sports for fun - wasting your money / promoting violence
-- Traveling for fun - you are destroying the environment
-- Any entertainment shows - promoting bad habits
etc.. etc..
You can extrapolate 'what I don't like, must be bad for humanity' to almost every product of leisure activity out there.
At some point, for some, unless you are living like an Amish or in some kind of 'Puritan' way, everything else you are doing is bad and you are a bad person, and that platform that enables it (Radio, TV, Online Apps, Arbnb, Uber) must be bad and needs to be abolished.

In any case, a lot of those can indeed be considered bad. Like professional sports. Participatory sports on the other hand, foster community, improve health, and entertain, all in one.
Watching movies, or the general category, art, nourishes the soul, allows us to live vicariously other people's perspectives, and builds culture. Watching crap movies, made for profit, who turn their audience stupid (or pressupose their stupidity), on the other hand, can be considered bad. The same can be said of spending hours every day watching TV.
Meth also makes for great profits.
