Which is why when some people complain that a movie "changed something from the comics" it's so frustrating. I think it's better to take inspiration from stories in the comics but adapt them to work in the film medium. They've had great success with that formula so far.
I have no problem with adaptations, especially when it comes to comics. Its the execution and reasoning I have issues with sometimes. As far as the MCU goes I'm fine with about 95% of the adaptations that were made.
