This week's new DVD releases range from the odd to the odder.

Cloud Atlas, Grade B: Events and actions in one time period have an effect on past and future eras. Tom Hanks stars. Not since 2001: A Space Odyssey has a film come along that's such a marvel of moviemaking and a frustrating test of comprehension as Cloud Atlas.

The latest work by Andy and Lana Wachowski, the minds behind The Matrix, reimagines the art of moviemaking by creating a product that finds cohesion in confusion, distinction in disorder and symmetry in asymmetry. It takes an omnipotent look at how actions affect past and future generations as told through six stories set in diverse time periods covering a 500-year span.

Unlike the original book by David Mitchell that was generally linear in design, the Wachowski siblings, along with Tom Tykwer, have written a script that bounces forward and backward through time, never resting too long in one era.

It's easy to admire the brilliant craftsmanship that went into the making of the film. It takes a lot more concentration to fully appreciate the method in what appears to be six lifetimes of madness.

Dexter: Season Seven, Grade B: The season starts with the aftermath of the grand reveal at the end of season six. The exposure of Dexter's (Michael C. Hall) killer secret takes the first-rate series in the wrong direction. This series has always thrived on Dexter being able to work in the shadows.

What saves it is the addition of Yvonne Strahovski as the mysterious Hannah. The awkward emotional games she plays with Dexter push the show to new creepy levels.

The Blu-ray Disc and DVD sets include all 12 episodes plus bonus material.

Liz & Dick, Grade D: The stories that came out during the filming of this cable movie about the explosive relationship between Elizabeth Taylor and Richard Burton were more interesting than the actual film. That's what happens when you cast Lindsay Lohan.

The film looks at the turbulent relationship that made the pair the most notorious of the time. There are some interesting moments, but they get buried by the uneven acting and uninspired camera work.

Pick up a Taylor-Burton movie instead of wasting time on this weak effort.
