Some comic fans don’t have the time to keep up with modern continuity, and it’s easy to see why - the constant cycle of comic book deaths, resurrections, and character changes can make things rather difficult to follow.
Fortunately, it is easy for fans to catch up with their favorite heroes, but that doesn't mean the content won't shock them. Anyone trying to catch up on the Hulk’s story between the years 2016-2018 may be incredibly confused and full of questions, like "Wait, Hawkeye killed the Hulk?" and "Oh, so the Hulk is immortal now?"
Now referred to as the Immortal Hulk, Bruce Banner comes out of his brief time in the afterlife a markedly different character. He’s still big, green, and angry, but there are other convoluted factors involved now, and any casual fan will appreciate a set of “Cliff’s Notes” to help them understand what’s going on.
