From a review of The Adventures of Young Indiana Jones, Volume Three - The Years of Change at Blogcritics:
The First World War is essentially over and continues for only the first two episodes. The intrigue of that war and what destruction it wrought on a whole generation still make it the most interesting backdrop for these Indiana Jones stories. The first one, "Tales Of Innocence" is a simple tale and maybe my favorite in this collection. The two stories - Indy and Ernest Hemingway falling in love with the same woman and Indy and Edith Wharton developing a forbidden attraction to each other while Indy searches for a traitor - are light on the surface but that belies a hidden depth. These unrequited loves hint at what will become the post-war "Lost Generation." After what Indy has seen in the War, what meaning will there be in life? And how does he truly give his heart when he's seen so much death and destruction?
