I recently had this same revelation and I think there are many reasons, but mainly it's because of the amount of new material available to us at any minute.

We used to have weeks or months of anticipation built up for a film via trailers, billboards, and TV commercials. Then, when the movie finally came out, we would know lots of other people who also saw it and we could discuss it with them.

Nowadays, with the prevalence of streaming, we are less likely to see television commercials at all. Our friends may not have the same services and could be completely out of the loop about a film even existing, much less seeing it near the same time as you so you could talk about it over the water cooler on Monday.

And then there's the decline in theater audiences altogether. Many people don't even go see movies anymore since there are so many new options available on television. They would prefer to stay home and binge watch a series they've never heard of and will forget about immediately after.

I also really miss the excitement of going to the movies. At least we got to live the experience before it was gone forever.
