You will need to suspend your rationale brain to accept that an obviously aged and physically deteriorated man can repeatedly go toe to toe with 20-something, buff, well trained soldiers and win. Then again when a much younger woman who shows nothing but distrust and dislike for the main character suddenly reverses her behavior and drags him to bed. Fight scenes are very poorly choreographed Flashback scenes, used to actually explain the plot are so suddenly and poorly edited in, they leave viewers to wonder if they accidentally changed the channel and are now watching a different show.
