The first one is the best of the series for sure.
The best thing about the movie is the way the main character is written. He is an invincible force who is absolutely unwavering in his virtues. He is an essentially "perfect" character. He never strays even once from being the absolute pinnacle of helpfulness, empathy, generosity, patience, devotion, gentlemanliness, fearlessness, or even humility, even as he shows full competence in everything he tries. And despite all this, he's never unlikable. You root for him the whole time. He is basically the platonic ideal of a leader in every sense of the word. From a storytelling perspective alone that's one hell of an accomplishment.
