We're probably getting close to exhausting the list of characters I can imagine finding lovable ("I love everything Aguirre," anyone?). So I thought we could try applying the format to some non-human subjects.
By "reunion," I mean not only everything that happens on the day Jack shows up, but also perhaps going back to when Ennis gets the postcard and ahead to the "sending up a prayer of thanks" scene. In addition to onscreen moments (eg, I love the expression on Ennis' face when he looks out the window and sees Jack drive up), we can also mention more abstract things. Such as:
I love the fact that, for four years, Ennis had missed Jack and longed to see him again but had undoubtedly long since given up all hope. Now that it's actually happening, he can hardly believe his luck.
