“The Last Three Days” (** out of four) was a tepid time-travel thriller in which a rookie undercover cop (Robert Palmer Watkins) gets mired up with a dangerous underground crime syndicate and wakes up to discover he is missing his partner, his wife, and cannot remember the last three days of his life and has to struggle to piece things back together from the recent past in order to save his and everyone’s future. Needlessly confusing thriller has various story fragments from “Memento” and also “The Bourne Identity” but comes up short; at least it moves fast and is relatively lean at an hour-and-26. Not bad but you’ll likely forget this within the next “three days.”
