I don't Meemaw being ultra conservative in Young Sheldon. She just was overly protective of Sheldon towards Amy. That would fit with current Meemaw. Maybe I need to watch The Big Bang episode again.

RDJ is fabulous no matter what role he plays. He will do a great job. That being said, I loved the humor he brought to Iron Man and that doesn't fit into Doctor Doom's character. Will miss that.
