Jerusalem’s a messed-up place, what with everybody who lives there wanting to kill each other and everything. That’s my 17-word synopsis of current geopolitics, as well as the 2005 film “Kingdom of Heaven,” which takes place 900 years earlier, when Jerusalem was just as messed up as now. Except back then, dreamy Orlando Bloom served as a knight who represented all that is good in men. Because of that, all the non-dreamy men want to kill him. So, basically, people haven’t learned a damn thing in the past 900 years, which this film goes to great lengths to remind us.
