This is an excellent moving film. Morgan Freeman's naration is excellent adding a real feeling of care and warmth for the penguins. It is highly recommended! The content of the film definitely deserves 4 stars at least and this review should be read in this context.
So why only 3 stars? This is a review of the Blu-ray version of the film. So what is this film like in HD (bearing in mind that this comes at a 200% premium compared the standard definition version March of the Penguins - Luc Jacquet )? The HD adds nothing. At times it seems more like an upscaled DVD. Certainly compared with the same material from Planet Earth on Blu-ray this is very poor. Bearing in mind that this was shown in the cinemas on a large screen this must be a flaw in the conversion. What a let down as it is not hard to see how beautiful this could have been.
