Chewie is a great character with a rich history outside of the movies in the expanded universe material, and while I get it’s a challenge to give meaningful arcs to a character who can’t speak galactic basic, I think R2-D2 has gotten more overall screen time than him.
Even if Chewbacca has to play the second banana, it’s still far more attention than he has gotten as a character in past Star Wars movies.
Solo sequels are one of the only logical ways to expand his part in the franchise, so make it happen and we can cross our fingers that a screenwriter will figure out how to give Chewbacca a great arc.
