At the center of everything is Reba, who put Brock through dental school, had a trio of kids with him, then loses him, inexplicably, to sweet but simple-minded Barbra Jean, a hygienist. Yet he isn't really gone: Brock's emotional ties to Reba remain powerful, and he is often full of regret over whatever is driving him away. More challenging is Barbra Jean's needful attachment to Reba, which gets particularly difficult when the former keeps turning up at sensitive times, such as a visit from Reba's parents (Barry Corbin, Dorothy Lyman) and during Cheyenne's Lamaze classes. While coping with her own divorce, Reba keeps busy helping Cheyenne and Van set up their lives as newlyweds, a tricky business since both are still in high school and so many people--the principal, Van's parents, Reba's neighbors--disapprove and assume the worst about the Harts' morals. Still, every episode ends with the feeling that everything is going to be okay in Reba's world, even if she has no idea where so much change is taking her. Country superstar McEntire proves a very capable and attractive comic lead, and the rest of the cast, including Mitch Holleman and Scarlett Pomers as Reba's youngest kids, are caught up in Reba's appealing chaos. --Tom Keogh
