Typical. You wait ages for a new BBC sitcom named after a huge extinct creature and then two come along in the same week. I'll be writing about Ashley Storrie's Dinosaur later but first we must address the elephant in the room. Or should we say Mammoth, as that's the title of this new sitcom which, without ever really mentioning it, is largely a comedic reverse-spin on Life On Mars, but set in a school in Wales where teacher Tony Mammoth returns to work having been dug up in 2024 following being buried in an avalanche in 1979.
