Mexico: Earth's Festival of Life

It’s hard to convey how intrusive the commentary on this travelogue-cum-wildlife show is. The visuals are gorgeous, like something you’d see on a loop at a travel expo, a greatest hits of “ancient peaks” and “scorching sands” and “mysterious forests” in a land that is “a riot of colour” where “continents collide”.

These sentimental lines of narration criss-cross the footage like spun sugar. Put up with them and you will earn nice sequences about orchid bees and playful black bears and a lesson on how they make tequila. But then, at the end, a self-congratulatory ten-minute coda tells how the programme was made.
