Based on what we’ve seen, I’m fine with the new guy as Han. It’s like people described the CG Tarkin. I didn’t buy that as Peter Cushing, but I DID buy it as the character of Tarkin.
I don’t buy this new guy as a young Harrison Ford, but I am buying him as the character of Han. He’s got the swagger, the attitude, and the charm. I can totally see this working. Granted, this is still all based on only a few seconds worth of footage from the trailers, but to quote NuHan©️, “I’ve got a good feeling about this.”
Now, I’m not yet convinced by Glover’s Lando. But we’ve seen SO little of him so far that it’s really hard to even begin to make a guess yet.
