Movie begins with major religious goof up

This movie was admittedly mildly entertaining (though different ending from the novel) and the heroine sympathetic, but how can anyone take it seriously when it starts out by having the ceremony for these three little girls called Confirmation when it is actually their First Communion? I'm not Catholic myself (though my husband is) but would have realized LONG before I ever met him what this particular ceremony was. Surely to goodness, if Hollywood is making a movie set in 1950's Catholic Ireland, they could check their basic facts a little better. It really wouldn't have taken much of a consultation. The movie thus lost all credibility for me early on. It seemed obvious to me that they just wanted to make a sort of college soap opera revolving around sex, and weren't concerned about genuine quality at all. This particular goof up is absolutely unforgivable.
