It is such a shame that so much effort went into the photography of birds in flight, particularly in formation, but also in a stampede and many other breathtaking scenes; but so little effort into finishing off the film. There are some sub-titles but not many. There is some narration by a Frenchman whose command of English is so poor that he searches for words during the commentary. The question that must occur to everyone watching the film is "How do you get such close up shots of birds in flight?" If you switch on the directors commentary it is so boring that you will probably miss the allusion to the answer. Essentially only 2 ways are vaguely described though it is suggested there were more. It could have been so much better with so little extra.
