Great to see I'm not the only person who saw Calvary. I'd have to say it's the best film I saw in 2014 (or at least, film that was released in 2014). I've heard people say that it's an anti-Catholic film (or at least Catholic Church, as per the sex scandals), but I'm inclined to disagree, in that the most decent person in the film is the Catholic priest, who while possessing his flaws, is a good person at heart. The theme of Calvary is, IMO, that religion (and not just Christianity) has its pros and cons, and that being Christian/Buddhist/Atheist doesn't make you anything in itself. Individuals are individuals. Religious belief, or lack of it, is a facet of being an individual.
So yes. I'd definately recommend Calvary. I'm not sure if I'd call it a "Christian film" per se (as its subject matter extends beyond religion), but if it is indeed a "Christian film," then it's still a stellar example of one. And this is coming from someone whose irreligious.
Since the topic has come up, it's already been pointed out that 'Prince of Egypt' is a good example of a film that uses Abrahamic lore to tell a story, and to that I say, yes. It's a good film, and you should definately see it. To mention another example, there's 'The Way.' Average, and Christianity isn't really the focus, but it still features. Might be worth a look if you're into character introspection.
