Seems like, at the French Dover landings, director Ridley Scott was trying to make a medieval Omaha Beach scene (like in Saving Private Ryan), complete with wooden replicas of WWII landing craft, underwater shots of floundering infantry helpless against a fusillade of arrows, etc.
Cate Blanchett/Lady Marian served as the obligatory woman warrior, but wasn't quite the amazon superninja standard in action flicks. I am surprised, however, that Scott didn't choose a more physically attractive female lead. She did give a fine performance, though.
Russel Crowe's Robin Hood was certainly heroic, but could have used just a touch more depth, IMO. Anyway, good flick. Go see it.
