Theatre Off Jackson's fifth annual Solo Performance Festival is packed with talent (Lauren Weedman! Troy Mink!) and continues tonight with an encore presentation of Matt Smith's All My Children, in which a character who looks and talks a lot like Matt Smith tracks down young people and confesses to being their long-lost father. Oh yeah: He's lying, in an awful and spiritually violent way, but he's smart and funny and self-deprecating enough to make this amoral cad almost lovable (and shockingly entertaining).
