The Eclipse Theatre Company ends its season of Lanford Wilson plays with the weakest of his three dramas about the Talley family. Revolving around fathers and sons, the piece is loaded with filial catastrophes: the looming death of the repellent patriarch, the younger generation's reluctance to take over the family business, the sudden arrival of illegitimate offspring, the death of a son in battle. Wilson's dialogue rarely transcends squabbling, but the ensemble work in Louis Contey's production is so good--cohesive but with each character sharply delineated--you'd think it was Chekhov. Pretty much everything about the performances feels authentic, right down to the Ozark accents. Through 12/18: Thu-Fri 8 PM, Sat 3 and 8 PM, Sun 3 PM. No show Thu 11/24. Victory Gardens Theater, second-floor studio, 2257 N. Lincoln, 773-871-3000. $16-$22.
