[MCU] What does the average person think of the Hulk - hero, villain, monster? How is he portrayed in the media?

The first time a wide public audience saw the Hulk was in Harlem, when he arrived with the intent to direct all his rage toward Abomination.  Next was in the Battle of New York; again in control of his transformation.  Before those two events, those who saw the Hulk were involved in the fights or a rare person or two who managed to get some of it on a phone camera.

After his rampage and fight with the Hulkbuster armor in South Africa, Banner comments that "the world just saw the Hulk, the real Hulk, for the first time."  Due to that incident, public opinion of the Avengers as a whole was becoming more negative.

So, he's had some bad public moments, and people will certainly be startled if he rips apart an Ultron and roars in their face, but most of the time people see him there's a bigger threat that he's fighting, making him a good guy.  The fact that there are children's toys and masks and drawings of him speak volumes.  Usually, he's met with roughly as much praise and criticism as the other Avengers.
