I thought it was entertaining. It does have this odd vibe--Iraqi tragedies played as Brian De Palma vomitorium extravaganza--but Dominic Cooper is so
commanding in both roles. And it just plays well as a thriller.
It does, however, definitely lose A LOT of steam after Latif escapes. Everything after--including the out-of-nowhere moment of revenge--is oddly flat.
The review I wrote when it was in theatres:
