Bruce Banner in the comic risked his life to save an innocent person
This is why the Hulk was heroic
David Banner in the show experiments on himself trying to gain super strength
They are not the same Banner, not the same person in the two universes
For this film we see Bruce do the heroic thing and get the gamma that way
For the MCU, the Ed Norton version, we see him experiment on himself
Which is disappointing
The MCU Hulk has a lot of the TV show in it, even the David B on the letters from Sam, the moving from town to town
And while Ed looks and acts like Bruce from the books, Mark looks more like David from the show
And the Don't make me angry line gets referred of course
