If you're looking for mindless action, complete with an explosion every 5 minutes like in a Michael Bay movie, this is not for you. The humor is sparse and dry, it's not for comic relief to make you feel better. This is his origin story. It's slower paced so you can understand where he comes from and what drives him.
This Bruce is emotionally-psychologically complex and introspective. This Hulk is the personification of his subconscious; of all his repressed trauma. It's catharsis and acting agent for all of Bruce's pain, anguish, isolation, his hatred in being dominated by Talbot and Ross, and his frustration over a wasted (then thwarted) relationship with Betty. And his agitation over an estranged, obsessive Father, and repeat unwelcome attempts to kindle a Father-Son relationship. His Mother is the ghost of his subconscious mind, and he's haunted by her loss. This loss defines him. He's a dark character, and is given an appropriately dark tone, with a slower pace to match. In the few quiet moments he has to himself, you're given his humanity. He'll try to calm himself down, if he's allowed to. There's glimpses of heroism in him, as when he saves Betty (and a nondescript pilot), but he's no hero. People are only afraid of him here. He's vulnerable and tentative with the one person he cares about, which is rather wholesome lol.
Cinematography wise, it's gorgeous and original. 10/10. Haven't seen anything like it before or since. Many people think the way it's shot is jarring and obnoxious; it flows like a comic book. The CGI was before it's time, it looks better than Mark Ruffalo's. He's a vivid shade of green that will play with some people's depth perception. Some complain this Hulk is "baby faced"...as it's personification of Bruce's 4-year old traumatized mind (and is 15ft tall with more intense sound production than any Hulk after), I don't see that as a con. The dialogue can be quite profound, which some will think cringeworthy for a 'Superhero' (he's not here) movie, but that's your prerogative.
I'm happy this is getting a renaissance of sorts, it deserves it.
