This is part 2, continued from part 1.
We stopped after the movie jumped ahead in time for 30 years. What happens then is astounding and simple. The movie just moves on and follows old Joe as he travels back 30 years to his past, where we then follow him as he follows young Joe doing all the things we saw already. So while structurally the movie shows us the same events from a different perspective, narratively it just keeps on moving along, without any actual jumps anymore. It does leave out some crucial information, though, but we don’t know that yet. What we feel is sympathy for old Joe as he tries to save his newfound happiness with his wife (Xu Qing). It’s a relatable motivation up till this point and it’s important to see that the movie takes us there, so we later have to ask ourselves how far we are willing to go along with this character. We get some fun moments where old Joe doesn’t understand young Joe’s actions, which is a clever way of showing how we distance ourselves from who we were the more we grow older.
