I think recasting is worse. It would get a huge negative reaction and wouldn’t feel the same. I can’t think of any movie that recast a famous role for a sequel that wasn’t awkward, and none of those roles were as iconic as Carrie Fisher as Princess Leia.

I second this. People balk at recasting famous roles, but I think using CGI is worse unless we can do it absolutely flawlessly, and we’re clearly not at that point yet.
