Me too.
I love Shuri (and the actress who plays her). I would absolutely support her taking up the mantle (and the suit they came up for her in the video game footage is awesome).
But T'challa was also such an important movie character and real beacon of optimism and progress for so many people (especially kids). I also think it would be a real shame to lose the character (even if it obviously means re-casting) after only 1 solo movie.
So yeah, I don't what I'm rooting for. It's a tough decision for Marvel, for sure.
