Are any of the characters in The Bear likeable?
Everyone is a misfit to some extent and the stressful nature of the show shows them at their worst most of the time. It's a show where the primary draw is tension. There's often a sense of impending doom, and the resolution/release usually just sets the clock back, instead of dealing with the underlying problems.
They're all likeable.
Even Richie who you can't stand in the beginning becomes a sympathetic figure as his character arc unfolds. You see early on that he's not just an a$$hole and he's dealing with a failed relationship, failure as a father, not having purpose, and coping with the loss of his best friend.
That's the beauty of the show's storytelling. All the characters have personal struggles that are understandable and relatable by the time season 2 wraps up. You're invested because you want to see them turn it around and succeed.
