Does it though?
Because I don't think costs can be discounted here. Because as ticket prices have rose many are deciding to wait to see it at home due to it now costing way over $100 for a family of 4 to go to the movies. Whereas in years past, like when the MCU first started, one could go to a movie for half that on average. Basically unless its an event film you're not going to get the masses out. So forget the average run of the mill mid-tier MCU movie. And its because ticket sales have continued to plummet year-after-year for the past 2 decades, something that many of us have talked about before, and something I continue to bring up because I feel its important in these conversations.
I mean just look at some of our fellow posters here, many have commented that they will just wait to watch "insert the name of the latest movie here" at home. And the number one reason given, "its costs too much to go to the movies".
Ticket prices have generally outpaced inflation, especially now for premium seats. For example someone spending $10 on a movie ticket in 2008 when RDJ said "I am Iron Man" should be paying ~$14.50 today, but most are paying over $20 for even non-premium seats.
So unless someone is going to a matinee show solo on a Tuesday and not buying any snacks, you're probably not getting anywhere close to what they paid in 2008.
So no just doing an inflation adjusted look doesn't actually tell you anything about how people felt about anything, not when less people go to the movies today than they did even 5 years ago let alone 10 years ago.
