I didn’t see the original, but it must have had more juice and substance than this limping sequel, also set in the early 70s and directed by Howard Zieff. Valda Sultenfuss (Anna Chlumsky), now 13, decides to write a school paper about her mother, who died when she was born, and travels out to Los Angeles from Pennsylvania to stay with her Uncle Phil (Richard Masur) during spring break and learn what she can. Dan Aykroyd and Jamie Lee Curtis are back as her father and stepmother (the latter expecting a child), but the emphasis here is on Valda’s investigation, which Janet Kovalcik’s script makes into a fairly meandering and sprawling affair. With Austin O’Brien, Christine Ebersole, Angeline Ball, J.D. Souther, and Richard Beymer. (JR)
