Yes 'Route Irish' is the name of the road to Bagdad International Airport, and is seen as the most dangerous road etc. However, we see very little of that and as others have commented, there is very little action indeed, in this film.
Ken Loach is an excellent director and I am a loyal fan, this film though does not really deliver what it promises to do, I may have been generous in a four star rating. So what is wrong?
Well it is about the death of a private security guard in Iraq (played by `comedian' John Bishop), and his best mate, who does not believe the official version. He sets out to find out who really killed his friend. He has been in a fight and whilst awaiting trial has his passport confiscated, therefore the entire story is based in Liverpool. He uses the internet and meetings with his former bosses to uncover more and more. The previous events are told in periodic flash backs, and are short but important.
This is a story about lies, deception, trust and profit. The private guards are referred to as `soldiers for peace' at one point, and not as soldiers for profit as is more accurate (they are on £10,000 per month). There are references to torture tactics and actual footage of fighting and victims from Iraq, but it does take its time getting there. The acting is all wsell above average and the whole thing is belivable but just a little unfulfilling.
I would like to pour praise on this, but I liked it more for being a Loach film, than being a film in itself. If you are a fan you may find merit here, if you are new to him, then you would be probably best advised to give this one a miss.
