I was surprisingly disappointed with Glover's performance as Lando in Solo. It felt like an impression of Billy Dee Williams more than an earnest take on the character. Donald certainly has the raw charisma that Billy Dee had, which is really all the character was ever about since we knew nothing about his backstory or personal motivations. So, not sure what was missing, but it felt out of place when I watched the movie.
As with any performance it's hard to know how much is due to the actor and how much from direction/editing, so I'm sure he can do the role justice. Assuming there's a good script and everyone else is doing a good job, of course!
