“Ex-Wife Killer” (** out of four) was a plastic romantic thriller about a vengeful ex-wife (Arianne Zucker) who seems determined to wreak havoc on her former husband (Jordan Belfi) and her new girlfriend (Marguerite Moreau) but after a series of bizarre events and occurrences, the girlfriend starts to suspect there may be more to their relationship and motivations. Derivative and predictable story won’t be too surprising for anyone who has watched a thriller before but it remains watchable. Final twist is pretty neat though.
