“Paradox Effect” (** out of four) was a half-baked suspense potboiler about a former drug addict (Olga Kurylenko) who witnesses a murder and is forced to cooperate with the killer (Oliver Trevena) to save her daughter’s life and this all leads back to an aging crime boss (Harvey Keitel) they all want to take down. Tense story is watchable but lacks the skill and suspense to really put it over and give it maximum charge. Similar (and inferior) to Michael Mann’s “Collateral.” Kurylenko turns in another strong performance; Keitel sleepwalks through his umpteenth role as a mob villain.
