Caroline Framke Chief TV CriticWatching “All Creatures Great and Small” feels like gripping a warm cup of tea and settling inside a very cozy, extremely British snow globe. Based on the immensely popular novels by Alf Wight (aka James Herriot), the series follows a 1930s veterinary practice in a sleepy Yorkshire town where farmers and vets alike gather every evening over foaming pints at the local pub after a long day’s work.
