this title is showing its age a bit. As with other older series it is in 4:3 format rather than widescreen though you can always zoom in a little if you want to. Image quality is better than the earlier Life on Earth series on DVD but like that series, this one would benefit greatly from being remastered for blu-ray. The radiophonic music is a little intrusive at times - like an early episode of Dr Who. There is also a rather silly "making of" doc by Miles Kington which is probably best ignored - thank goodness this comic tone has been dropped subsequently.
Having said that, this is a landmark series which is well worth another look if you have an interest in the subject. It starts in the mighty Kali Gandaki river gorge in Nepal, examines different habitats around the world and holds one's attention until the last episode which focuses on man's impact on the planet through overfishing and deforestation.
