Amen. She's a shapeshifter, not Mr.Fantastic. I love Liu, feel she writes a competent, cool, caring Gambit, but having him lose that exchange really, really pissed me off. How many times now has Mystique embarrassed Gambit??
I feel that as super fans of characters, it gets easy to slip into wanting our favorite to be a Gary Stu. But when the story is written from the perspective of the protagonist, then the characters need to have adversity and not just win all the time. I find a story far more engaging when the hero has to struggle a bit to come out on top or sometimes not at all.
Like in Star Wars. If Luke just beat Vader on their 1st duel, it would have completely rendered Vader as incompetent for the next movie, a mistake I feel the newer Disney films made with Rey and Kylo. It made the villain non threatening and I found myself not rooting for the hero. I just like good character driven storys where the character is respected even if they dont win everytime.
I certainly have seeen my fair share of writers disrespect Gambit as a character, but I just don't see it in this particular story.
But I'm trying to remember, what other times have Mystique and Gambit fought besides that time he was Death all those years ago? I remember a scene before he was death where he was giving her a good fight, but maybe I'm missing some story's?
