I agree; I like summer films but most of the time there is social media in my phone. I would be a good take if such films are targeted to older audience.

We are still in the winter, so summer movies do not play so much.

That's just a massive generalization. Young people are the ones more likely to lineup for those Thursday preview showing. Tons of young people go to watch movies in the summer. That's about the only time kids, teenagers, 20+'s have a break from school and college to watch movies whenever they want. For adults, it really shouldn't matter whether it's summer or winter. If you are working, you will still be working during summer. If you are not, you will have the time watch movies whenever you want. But the time of year is less influential to when adults go see movies.

Tiger, here's a rebuttal.
Obviously someone is watching these summer blockbusters, or studious would stop making them.
If you want sophisticated films, go watch one.
There are always indies out, all year long. Do some hunting online and go see one.

That'd actually be nice for a change. It'd make the summer season less bloated with all these uber-expensive releases that are either sequels or superhero movies. As it is, the most acclaimed movie so far this summer is a movie meant for the +45 crowd: Hell or High Water.
What's missing in movies is same as in society: a good sense of work ethic and living up to ideals.
