Hulk was first seen in 2003, and now it's been 15 years. of course Hulk is going to have some changes. I think the changes that are shown are absolutely correct.

It is completely part of the character, I mean, of course you have changes too during the years, and if it's been 15 years, he also have to look older, don't you think so? At the end of the day, Hulk is a normal man.... But that can transform himself xD

Why has the Hulk had multiple Facial changes ??

MCU movies have that Disney money, and can thus spring for the best plastic surgeons in town

Okay, you made me laugh this time xD

With all the changes between the Hulk and Banner he had gone through in the last 15 years. I'm surprised that Banner doesn't look like an accordion.
