Actually upon my second viewing I noticed something about that final fight that I missed the first time. Anyone else notice how the cure made the Hulk less aggressive especially when the Abomination hops ontop of the helicopter after it crashes. If you look at his face there's something real subtle there, hulk looks at him without any emotion then you can see he's thinking to himself like "he'y I'm supposed to be mad" then he starts growling passively, the f/x in that little part were great.
Really the whole time after the Helicopter crashes, Hulk's body language is so relaxed, like he doesn't really want to fight, which also explains why it took so long for Banner to change when he was freefalling and why he evidently can control his transformations at the end, and why hulk spoke more clearly than the first scene, the cure made him a bit more mellow and smart (even though he found it in himself to box with "police car" gloves

) I think if they squared off in the beginning of the film Hulk would've strangled Abomination to death possibly.
