Always fascinating developments
“Once Upon a Time: The Complete Fourth Season” has tapped into the goldmine that is “Frozen” by introducing the characters Anna (Elizabeth Lail) and Elsa (Georgina Haig). The death of their parents is shown and there’s an impressive sequence set in Arendelle. We also learn Elsa’s reason for being in the Enchanted Forest. The chemistry between Ms. Lail and Ms. Haig is strong, and they both manage to channel their animated counterparts successfully. Disney has milked the “Frozen” property endlessly to squeeze every possible dime out of audiences thrilled with the story and characters, but this prequel is engaging as it provides an interesting back story. More CGI than usual for the series is incorporated.<br /><br />The season focuses on the battle of the forces of good and evil. In other story lines, Regina has found true love with Robin Hood, but is thrown for a loop by an unfortunate twist of fate. A banished Rumpelstiltskin enlists the Queens of Darkness — Maleficent, Ursula, Cruella De Vil — in a dastardly scheme to rewrite their own stories and corrupt the Savior by turning her newly blissful heart pitch black.<br /><br />The series manages to stay fresh with its ever intriguing reimagining of classic fairy tales, skewing them just enough to make them seem fresh and providing greater depth than the overly familiar originals. The show’s appeal is widespread, since the basic tales are known to practically everyone. Kids will enjoy seeing their favorite characters come to life while adults will enjoy the cleverness of the writing and the spirited, often tongue-in-cheek performances.<br /><br />Bonus features on the Blu-ray release include three behind-the-scenes featurettes, bloopers, deleted scenes, and audio commentaries.
