Disney built a whole Marvel studio complex in Georga, USA moving production away from earlier Marvel production in Hollywood and union labor (and chasing tax breaks). Now they're tearing down that down to move to an even lower cost site in the UK. Marvel movies have been dropping in quality all while the execs pinch pennies and opt for lower and lower cost labor. Your data seems to support my assertions more.
"Tangents" of discussion are the whole point of a conversation I'm not approaching this as some competitive one upsmanship proving ground - I don't think either of us are going to get "proof".
