Evolution of the Marvel Cinematic Universe

Hi everyone, I recently saw Thor: Ragnarok and I am slightly uncertain of how I feel regarding the shift that the Marvel Cinematic Universe is going through. Now, this is certainly a debatable topic but this is the way I see things.

It seems to me that the MCU is going through a period where it is almost recycling its characters. It is taking the heroes we know and love away from their contexts, tearing apart personal connections that made the characters relatable. This is probably so that the infinity war arc is unburdened by each individual characters personal dilemmas and focus solely on beating the big bad Thanos. My issue with this is that we are no longer watching characters grow and develop, we are watching a situation. It's certainly an entertaining situation with a good enough plot, but it seems to me that the characters are becoming slightly more shallow.

Thor: Ragnarock was very entertaining and funny but getting rid of Jane so offhandedly irked me. We watched two movies where Jane was a very major character and we don't see how the break up happened, no flashback, no nothing, Thor doesn't even seem affected by it. Another example of this shift, is the pairing up of Natasha and Bruce. Not that it happened but how it happened, we barely see the two characters interact and suddenly Natasha can stop the Hulk. Really? It is making the characters simpler and more predictable. Narrowing the characters down to a few basic characteristics (Eg, Spiderman is your basic teenager, Villans are 2D generic villains) and we miss out on all the wonderful, unique things each character has to offer.

In Thor: Ragnarock, Asgard is blown to smithereens and there is a joke about the foundations being unsalvagable. Which is exactly what I feel is happening to the foundations of the MCU, and maybe I am the only one who sees it this way and please feel free to disagree in the comments. I would love to hear different opinions.

Thank you :)
