HelloGreedo’s trailer review. One of the more level-headed reactions/reviews on YouTube.
I also agree that the most important part about Ehrenreich’s performance will hinge on his attitude, not how he looks or what he sounds like, but if he manages to capture the attitude of Han Solo. And of course this is a backstory film, so he won’t be exactly like Han in the OT. This one should be less experienced, cocky externally but less sure of himself internally.
