This movie started off a bit disjointed, it was hard to figure out who the main hero was. The captain made some ridiculous mistakes that just wouldn't happen, throwing a secret dossier to the ground in an emergency and hiding it in a tin instead of stuffing it down his shirt.
But where the movie really falls down is when the soldiers are forced to enter the tunnels. I've read a bit about these tunnels, they were incredibly narrow and the tunnel rats all had to be really small guys who could only crawl through them. These sets had six footers walking through them with plenty of room, totally unrealistic, but the worst thing was the flat floor, so obviously a studio set.
