Hulk is one of the greatest fictional characters ever.
at first glance Hulk might seem like a boring character, people often confuse him with a plot devise too, i mean a big green man who smashes things? sounds kinda repetitive, but really, it's not. Truth be told, you can't like hulk without liking banner, because it's the dynamic that really draws you to the character. Banner is a a wimp, he is really weak physically, yet he is put in charge of one of the most powerful beings on earth, and how does one deal with that? I mean how can this weakling control such a powerful beast ? thing is, banner is the personification of Will and Strength of character.
Hulk is everything banner has locked up his entire life, and the funny thing is, he never gives in, he always knows that giving in to the rage might cause some harm to others around him. this shows how powerful he really is, the "Strongest there is" line which hulk frequently uses is tied to banner, because it's his will power and Raw emotions which gives the Hulk power. We've all been there, we've all wanted to cut loose before, there is always that voice that keeps telling you that you really want to punch someone in the face. now imagine that only multiply it by a 100, and you might understand banners situation. Banner and Hulk hate each other, which means that in reality Banner hates himself, or at least This "aspect" of himself. Hulk could fight the biggest baddest villain in the Universe, and still the greatest Foe he ever had is himself, this "jekyll and Hyde" concept doesn't always work, but it does here, because Banner's Sympathy is what makes hulks rage so awesome, and it's hulks rage what makes banner sympathetic.
But the greatest thing is that Hulk himself isn't a monster either, he never hurts the innocents, and there have been multiple times where he has protected the people who had called him a monster, this shows that even at his worst, hulk is by all means a hero. This all comes from bruce banner. you can imagine his mind as a huge hallway of doors, with each door holding it's one secret(aka Hulk). did that image since in? good, because it's important. Hulk is a type of character you can't get bored with, which is funny because most people would disagree with me, but then again most people haven't read his stories and have no idea what they are talking about.
The writers did a very good job of giving Banner and personality disorder because that way we can have many versions of the hulk which manifests based on the different aspects of banner, therefore giving each hulk his own distinctive look and personality. We have Joe Fixit who represents banners wild, Brash teenage self, and we also have the traditional Savage Hulk who has a heart of gold yes is always angry and misunderstood. My personal favorite would be Green scar, a Noble hero who would sacrifice himself for his family and friends any day of the week. This brings me to my next point, with a character like hulk, he can be written in any genre. it could Be dark and gritty or it could be light hearted and fun. and IT would work, because when you have a character like superman, he best works best in fun light-hearted stories, but with hulk, that doesn't matter.
i've gone a bit of track here but the point is that hulk is an awesome character, the kind that has substance and depth. People can say hulk is boring but if that were true he wouldn't have had an ongoing for 12 F*cking years.
"Then why do you suddenly look scared? Maybe you see that you could be ten times stronger than Hulk, and it still would not matter. Not when all Hulk has to do is become ten times as mad!!"
