That was the Marvel once. Serious, dark and gritty. Characters with tragedy and struggling. Not a child movie. No jokes popping out at every 3 seconds. You can see the seriousness of events, troubles of the characters. It's not BULK from Avengers and other movies. It's the Incredible Hulk with the best Bruce Banner... One of the bests of MCU...
