If I'm going to face down a dragon, Mob boss, evil corporation, or a demon from the 7 circles of hell or dystopian dictator, etc, it's not going to be to rescue my buddy Herbert, or cousin Jimmy. The best they are going to get are my harsh words and heavy disapproval muttered under my breath as I go into hiding. But if I had actually found real love and that was snatched from me I would move heaven and earth attempting to save her. So that is where my characters' motives come from.
However, I see the complaints so often now, buzz phrases being stuff like "manic pixie dreamgirl" "heroes reward"dreamgirl," "hero's reward," "nerd wish fulfillment"fulfillment," "women in the fridge"fridge," etc, etc.... Why is writing a love interest for the hero so widely ridiculed?
My issue is I enjoy those stories, they seem more realistic to me from the point of the hero. How can I write a story with a love interest without running into this kind of criticism?
