“Shotgun Wedding” (** out of four) was an utterly dumb romantic comedy about a bride and groom (Jennifer Lopez and Josh Duhamel) who gather their families together in Bali for an ultimate wedding reception but plans change when the wedding is taken over and held hostage by pirates and they find they have to put their differences aside to fight back and take back their wedding day. Needlessly contrived and silly, with only the good-natured performances of the cast to keep it afloat. Lopez gives 100% as usual with her effortless charisma but it’s really thin stuff. Lenny Kravitz has a minor role as Lopez’ ex and Cheech Marin shows up as her dad but they still can’t keep this from firing blanks.
