For a show with a total length of around eleven minutes per episode, you wouldn't expect much in terms of character development or depth. This is one reason why the show is so brilliant, though. After a first season that merely hinted at the innermost problems of the characters, instead parodying the various misconstruing and hypocritical rules of Christianity, the show takes a new direction entirely and this takes a backseat to the characters and their problems and secrets. The relationships between each character are diverse and interesting to see, and it is forgiveable that there is little comedy in these sections because it is obvious the entertainment is present in a new way. The fictitious town of Moralton is a hotbed of interesting personalities and characters, and the far best part is the main character himself. Orel is not only innocent and ignorant of the mistakes of his friends and neighbours but he actually believes the self-satisfying rules people put forward for the sake of religion, making his eventual loss of trust in his family at the very end of season two all the more fun to watch and unforgettable.
Season three takes place before the events of the last few episodes of the previous season, and delves deeper into the personal lives of the characters. And by the characters, I mean every single damn one!
Two characters who do nothing but give each other friendly glances in Church twice a season get an episode entirely devoted to their quirks and misgivings. The gym teacher's homosexual love for Orel's father drives him almost to the brink of murdering Orel as part of a ritual to gain his affections. The "Bully" character who was important for maybe five minutes of the first two seasons and a woman who existed purely for a quick joke about a persons' voice over the telephone (She holds her nose to sound less like a man) have an episode to reconcile with each other while her adoptive son searches for his real mother.
The greatest part of the series is how all the above characters and the rest are not only believable, but lovable despite their murderous or outright evil tendencies. You'll want everyone to get a happy ending and be reduced to tears on the occasions where they don't. By the end of everything, you'll have fallen in love with the little town and it's people. I recommend this show to all, religious or not.
