Having read somewhere that Estevez claims this as a remake of 'The Wizard of Oz', and that Sheen is a committed Roman Catholic, I expected to have religion shoved down my throat. Most certainly it was there. But not in the least offensively so. At one stage Tom (Sheen) meets a priest wearing a yamulka (to protect his head scared by surgery). The priest offers Tom rosary, which Tom returns later saying if was 'effective'. The Irishman (Jack) with writers' block initially refuses to go into a the cathedral at the end of the journey, but later relents and is seen wracked with silent sobs. It required no explanation; the audience brings its own feelings and thoughts to this scene. Both the Dutchman and the Canadian woman were inadequately fleshed out until late in the film. Joost says he is 'doing the camino' because he wants to lose weight. He eventually concedes that his wife refuses to have sex with him because of his weight. And so he walks the camino ... not very convincing. The Canadian woman (Sarah) was in a relationship when she agreed to have a fetus aborted to please her partner. This has scared her. However, there is an entire scene devoted to her hearing her daughter's voice ... not very convincing. The Irishman is the most convincing. The scene in which he is introduced is cringe-worthy, but he grows on one because we see him working his way through issues. He takes notes, and asks questions. The scene with the credit card is excellent, both parts of it.
And Sheen? I am a fan, so take this with a grain of salt, if you are so inclined. He got angry, he was sarcastic, tears flowed, he was pensive. But, all in all, it was a bit like watching Martin Sheen's home movie of walking the Camino. That sounds like a negative, and I guess so. However, I enjoyed the film, even though at the 2/3 point I got bored feeling that it was dragging. But I enjoyed the characters that joined along the way. I enjoyed meeting the 'locals', and I especially enjoyed the landscape and the weather.
Estevez dedicated the film to his grandfather, Francisco, who emigrated from Galicia to America many decades ago. So the family voice is quasi-european. I think the film might have been more enjoyable (for me) had it been made by european resident film-makers.
