I am really baffled a bit by this talk of Widow being ruined or even of the "forced" "romance" of Tasha and Bruce. I saw Widow being a kickass heroine doing amazing stuff all through the movie and her capture allowed the team to find Ultron cuz even held prisoner Widow found a way to help the team, and even though it is kinda ridiculous her, Hawkeye and Cap were all one shotting drones. As for the "romance"? What romance? They weren't in a relationship. This was two adults with an attraction that was all for naught, as it was explained in the film, at least that's what I got. This happens to people in life. Widow explained her attraction to Banner and even why his fears of what being in love with someone and the possibility of family could mean and why it would not matter because of what was done to her in The Red Room. And Banner didn't "betray" Betty. He wasn't romancing Tasha, he in fact thinks his whole romantic life is an impossibility, and that includes Betty, and he states why. In the end we see that he for the time being doesn't want to share his heavy burden with anyone. This seems very tempest in a tea cup to me.
