This is a thin week for new DVD releases. But, thin is OK when what is available is so good. Among the releases are those that will make you turn on a night light and test your legal knowledge.

“The Babadook,” Grade A-: Director Jennifer Kent has managed to avoid the common mistakes too many filmmakers make when they rely on gore to disgust and loud sounds to startle viewers. She’s created a movie that is terrifying without such gimmicks.

Kent has created a living nightmare that creeps into the lives of a single mother, Amelia (Essie Davis ), and her young son, Samuel (Noah Wiseman ). The Babadook is a killer entity introduced into their lives through a child’s pop-up book.

It’s been a long time since a creature this scary has come along in films. The film skirts just enough reality to make it seem possible.

Amelia continues to deal with the deep emotions of the death of her husband on the night her son was born. Is the Babadook just the manifestations of her mental collapse?

Samuel has become obsessed with creatures in the night looking to do him harm, either through his own twisted psyche or his mother’s emotional neglect. Is the Babadook a real creature attracted to the pain and fear in the house?

Kent offers both ideas in such a chilling manner that “The Babadook” offers plenty of haunting moments.

“JAG: The Complete Series,” Grade B: The box set includes all 227 episodes from the 10 seasons the series, which stars David James Elliott .

The series follows Judge Advocate General officers Harmon “Harm” Rabb, Jr. (Elliott) and Sarah “Mac” MacKenzie (Catherine Bell) and their team. This often includes dealing with cases involving military murder, treason and terrorism.

The show is an interesting courtroom drama, but it also has a string of strong performances by both Elliott and Bell. The show’s stars gave the legal drama more depth.

This is also a way to see how the current top drama, “NCIS,” got started. The Mark Harmon series is a spinoff of “JAG.”
