New to Blu: July 31-August 6

Critics agreed Sylvester Stallone’s latest is no knockout as a movie but were divided over the Blu-ray’s visual strengths.

In one corner: “Bullet To The Head comes with a very nice looking 1080p AVC/MPEG-4 transfer, which presents what is essentially a very gritty and dark film with a surprisingly bright, vivid, and colourful image that certainly livens-up the proceedings up quite a bit.”

And: “The transfer features inky black levels and contrast that accurately displays the full range of values, even in darker nighttime settings.

“Colours are sufficiently deep in a fairly limited palette, but sometimes the overall image can look a little desaturated or flat.”

In the other corner: “Bullet to the Head is a gritty, grimy actioner and its 1080p/AVC-encoded transfer is no different.

“Lloyd Ahern’s palette is caked in muddy earthtones, colourless hues and grimy skintones, and black levels are all over the place.”

And: “This is a reliable and faithful transfer …

“Sadly of a film that just doesn’t look very nice.”

But Blu-ray buffs won’t feel like committing the proverbial over Hari-Kari: Death of a Samurai’s specs.

“Presented in its original 2.39:1 aspect ratio, Hara-Kiri’s 1080p transfer looks fantastic from start to finish.

“The film’s natural colour palette holds up well with no bleeding (pun intended), black levels are strong and textures are crisp and defined.”

“Framed at 2.40:1 and presented in 1080p with the AVC codec, the transfer features satisfyingly inky black levels and a full and uncompromised range of contrast.”

“The transfer holds up very well with plenty of dimension and detail, excellent contrast and a very natural appearance to edges.”

The week’s only other new Blu-ray releases are Aerosmith – Rock for the Rising Sun, I’ll Do Anything: Jackson Browne Live in Concert and Robbie Williams Live at Knebworth.
