That's actually worse than what we got. Good change on Marvel's behalf there.In the farmhouse Bruce/Natasha scene, he originally firmly rejected her and told her off. This led to her being suicidal in the South Korea sequence which was the emotional core of that scene, when it was removed Joss felt that entire fight scene became a hollow spectacle. This is also why Widow talks about not walking away from the fight at the ending.
I can't even see how that makes sense for the character. I can see her getting pissed off, but not suicidal. I can also see her trying to compensate for her lack of powers by taking risky actions, but not letting her emotions over a man get the best of her when so much is at stake.
