Continuity mistake: A large group of students, led by Hilary Faye, Patrick, and Tia are snapping their fingers and dancing down the hall as they come towards Mary, Cassandra, and Roland, who are gathered near a locker. The large group comes to a complete stop and they greet the smaller group, who are shown briefly in the next shot. The following shot is of the large group; however, they are shown still walking towards Mary, Cassandra, and Roland, and they come to a stop for a second time as they continue the conversation. (00:57:30)
Continuity mistake: In the scene at the mall around Christmas, Cassandra moves her necklace to the side, under her collar. But with each shot it changes from either in front or under her collar. This happens again at the end before Cassandra, Roland, Patrick and Mary go to prom.
Continuity mistake: In the part where Mary is in the pool and hits her head on the ladder, the carpenter jumps into the pool with his shoes on, but when he swims by with Mary you can see that he does not have shoes on.
Continuity mistake: In the restroom, after Cassandra finds out that Mary really is pregnant, she hugs her. In the wide shot, Mary's face is in another position than in the close-up shot.
Continuity mistake: When Roland and Cassandra are at the cafe, right before they kiss for the first time, Cassandra reaches up to tousle Roland's hair. Watch the hand she uses; it has a cigarette right before she messes up his hair that disappears.
Continuity mistake: In the scene where Mary and the Christian Jewels are performing, it's clear she only has eye shadow on one eyelid.
Continuity mistake: At the school assembly, Mary plays the keyboard. She raises one of her hands in the air, then puts it back down - but in the next shot, it's up again.
Continuity mistake: After Cassandra says that she put something rotten (ham?) into Hilary Faye's locker, Hilary Faye is seen with her turtleneck over her face. Cassandra pulls it down a bit, but in the next shot it is up again and looks unchanged.
Chosen answer: No way to answer this without over simplifying or offending someone, but here goes... To characterize the three types by their one particular focus (and ignoring all other differences and similarities), Conservatives' main focus is for values/practices/whatever to stay the way that they have traditionally been. Fundamentalists want change from tradition to a stricter, more literal interpretation of the Bible. Evangelicals main focus is to be close to God to convert others to Christianity. Of course there are all sorts of combinations of all three as well. "Mainline" churches are the large, well-established, well-accepted mainstream denominations, e.g. Methodist, Presbyterian, Baptist, Episcopalian, etc. etc.
