I never perceived any therapist I saw or interviewed as distant and impersonal but it's likely the case because I have known many emotionally really not very demonstrative and engaged people in my life and usually get along with them without issues. I tend to be on the aloof side myself and don't care for small talk unless the other person initiates/needs it, so no surprise I am not bothered by T's not being warm and fuzzy (and prefer it). But I don't see such preferences necessarily as an issue unless someone has unrealistic expectations. If it is unrealistic, means life can rarely or never meet the expectations and/or it causes interpersonal problems in everyday life, then I think it is absolutely worth to work on it.
