Of all the shows I've seen, this is certainly One of them.
With it's mix of serious segments and trivial fun it really bridges the gap between Mastermind and Hollyoaks. If you're a person who liked Blue Peter as a child then you'll enjoy the One Show.
Hosted by the lovely Christine Blakely and the effervescent Adrian Chiles the show swings between hand bitingly dull and simply sublime. The two presenters dovetail together nicely, with Christine's cheer counter balancing Adrian 's dour melancholy.
An aspect of the show that has come under critique is their selection of guests. Seeing guests such as Sir David Attenborough sat next to Dom "Don't Get Done, Get Dom" Littlewood is justification for your license fee in itself. But getting them to improvise a conversation about a cat that can drive a quad bike is pure T.V gold.
In conclusion, The One Show is a difficult beast to review. It's the John O'Shea of T.V. A Jack of all trades but master of none.
