“Birthmother’s Betrayal” (** out of four) was a perfunctory thriller about an adopted young girl (Monica Rose Bentz) who yearns to find out and meet her real mother (Aria Pullman) but when she does- she finds out that she’s not exactly mommy dearest and is a real sicko who is bent on not only controlling her life but destroying it as well. OK cast and production can’t begin to save pedestrian script and predictable plotting. By now, you’ve seen this story way too many times for it to carry any surprise or shock value.
