“Jingle Bell Heist” (**1/2 out of four) was a mildly engaging holiday confection about two strangers (Olivia Holt and Connor Swindells) both who are up against a financial wall who team up to rob a large-scale department store on Christmas and find that in the midst of planning the robbery they are falling in love. Mix of gritty action, lighthearted comedy, and holiday romance doesn’t entirely work but is carried along by good chemistry and camaraderie between the two leads and bouncy style from director Michael Fimognari. Refreshingly quick and lean also at only an hour-and-40-minutes.
