Amen to that. I more or less agree wholeheartedly with your comment.
Even tho Women might be used a lot more often as eye candy than men, I do agree with that, there is in most Marvel movies a shot (often in the trailers) of the hero, topless, shredded.
"Money-grabbing sequels" As long as it makes money, Hollywood will keep milking any franchise they have, they are a business first and foremost. I think it is as idealistic as thinking that we are getting tired of "bad movies" and we only want "good movies".
"Subplots that set up sequels"
I would rather have subplot that set ups sequels like it has been done in the MCU than what has been done with the Transformers Saga where every entry stands on its own but on the long term, the overall story is so convoluted and non-sensical it just doesn't make much sense.
One point that could have been addressed is the scope of the blockbusters these days. I think people are getting tired of global extinction event, It has been done and done again and the general public has been desensitize and there's nothing really impressive in a city being destroyed. I think there is a general fatigue and it hurt films like Age of Ultron or Apocalypse. Whereas the smaller scale of Civil War or Deadpool made for a lot more engaging stories.
