They are busy every year, its just they are finally getting to OUR childhood actors.
John Wayne passing probably hit my dad like Arnie passing will hit me. Though he wasn't nearly as big a film buff as me so maybe not. But all those 40's/50's stars we saw in the "in memoriam" reel undoubtedly were equally beloved to fans from their era.
I feel like stars are "closer" to us because of the ease of watching old films now versus the pre or early home video era. I regularly spool up an 80's or 90's flick (though they can be hard to find in the streaming environment) but if I were going to Blockbuster still I'd stay focused on the new releases. Only during the summer would I delve into the back catalogue or be so bored I'd watch Turner Classic Movies or something on WGN/TBS.
My kid will sob if Mr. Beast dies....god have mercy on the youth of today
