Loved the movie. Alden's Han really grew on me and he kept getting better as the movie progressed. I liked his performance more than Donald's as Lando, actually. There were moments where he was great as Lando and others where I just wasn't as convinced.
Yeah, I thought Lando was really inconsistent. When Glover was on he was ON, but there were several moments where he just didn't click well. Alden surprised me with how consistent he was - he's not amazing, but I bought his portrayal of the character.
