One thing that really bugged me in this ep was Gambit climbing the ladder and jumping across to land rolling on the rooftop like a chump while Wolverine was already standing there. I realize they're kind of "one-upping" each other here but what the hell? Gambit's supposed to be one of the most agile X-Men, nearly on par with Kurt & Hank. He has to be to dodge his explosions. A few other things were off, animation-wise such as Magma turning back into Amara looking like a cheesy fade effect and Gambit tracing a circle on that rooftop being out of synch.
Anyway, regarding his "hotness", I wouldn't say he's ugly at all. He's certainly not a classical cartoon pretty boy like his Evo counterpart with the silly haircut, he's just not very stylized.
Look at Wolverine. Skinny legs, massive arms & chest and a sharp, angular face.
Now look at Gambit. Anatomically correct proportions and a detailed face that harken back to the style of X-Men & sPider-Man TAS.
Realistically sPeaking, WATXM's Gambit is a very handsome man. We're just not used to as many lines detailing facial feature's these days because animators learned that...
A) lines look like wrinkles
B) they make it more work to animate
