An American sniper and his spotter engage in a deadly cat-and-mouse game with an Iraqi sniper.

The Wall makes the most of its limitations -- albeit perhaps not quite enough to stretch its tight-focused action into a consistently gripping feature-length thriller.

'The Wall' offers a tense psychological thriller with a unique premise and strong performances, especially from Aaron Taylor-Johnson. The film's suspense is highly praised, yet criticized for unrealistic military tactics. The ending is divisive, seen as either shocking or disappointing. Some argue an anti-American bias exists, while others find a balanced view of conflict. Overall, 'The Wall' is a mixed bag with compelling tension and performances, but flawed by inconsistencies and a contentious conclusion.
