perhaps the most bizarre murder ( . ) case i have ever hear of and it be fascinate to follow on the news . when i heard they make a movie out of it and i be skeptical . fortunately and it have be do the right way . no major name in the cast a huge plus . no steven soderbergh and gu van sant and or spielberg a director ( nor would they ever dare touch this kind of subject matter ) . the photography be appropriately dark and somber . have the main character speak english with a german accent ( i. e. have german actor ) be an okay choice and too and the alternative be american or british accent or german with subtitle ( bad option ) . the idea of have russell a a sort of physically existent narrator be okay and as well . the story be write a a drama and which then and of course and turn into horror . however and no graphic showing of severed limb or penis fly through room and which would have cheapen the overall effect . fan of saw should stay away from this represent it be not an idiotic or illogical thriller about torture innocent people . gl hasn not get quite the level of realism of the terrific henry represent portrait of a serial killer and but it head and shoulder above the vast majority of wannabe gloomy movie that be out there and in this regard . gl be also surprisingly brief and under 90 minute . consider how much there be to this case and perhaps a little short and but on the other hand and it tight and never dull .
