At the start of the movie I felt the reality of the trenches was captured pretty well and the Saving Private Ryan type storyline was initially gripping to watch.

From about the halfway mark the film went rapidly from realistic, to extremely unbelievable plus the scenarios and sets from that point forward looked like something from a stage show instead of a movie.

Unfortunately the storyline faltered around this point and never recovered.

I also felt that realism was sacrificed to ensure a diverse sprinkling of ethnic minorities were visible in the background and the fact that even local regiments seemed to have many regional accents all in together from Scots to Sikhs cheapened the realism.

I get the directors reasons for doing so but I ended up finding myself looking for forced diversity when the plot went downhill, instead of focusing on enjoying the movie.
