“Agenda: Payback” (** out of four) was a tepid melodrama about a high-living sleazy executive (Sean Patrick Flannery) who is captured and taken hostage by a man who he screwed over (Eric Balfour) but all is not what it seems and the two men turn the table on one another numerous times. Both Flannery and Balfour are good and infuse this with all the electricity that they can but this runs out of steam and becomes tiresome even at only an hour-and-a-half. Remains watchable throughout but by the end, viewers may want a payback of their own.
