“Sinfidelity” (** out of four) was an obvious, empty suspense thriller about a married woman (Jade Tailor) who begins to suspect that her husband (Mark Jude Sullivan) is having an affair so she decides to have an affair of her own with her husband’s co-worker (Aidan Bristow) but this turns her life upside down when she finds out that he’s a vengeful sicko. Cleverly titled movie turns out to be yet another “Fatal Attraction” knockoff which is fatally illogical and predictable. Thomas Callaway’s cinematography is a definite asset but this is overall an affair to forget.
