This week's new DVD & Blu-ray

The Raid Be it the cop talking about when he shot some kid in Die Hard, or when they're discussing whatever the hell Treadstone is in the Bourne movies, or any time Arnold Schwarzenegger is trying to deliver dialogue, nearly all action movies have moments where things grind to a halt. Maybe they feel you need a toilet break, or perhaps the director gets bored when not doing the action and stunts part. There's none of that momentum-destroying nonsense here; there's hardly even time to introduce the characters. The Raid follows a Swat team fighting their way up through a criminal-run apartment block. That sentence is not just a plot description, it's practically the entire script – what would normally be the last 20 minutes of a decent action thriller is expanded, explored and turned into a whole movie. Welsh director Gareth Evans, following up his previous, well-received Indonesian martial arts fest Merantau, goes for broke. Waves of bad guys attack the cops and it becomes as much a horror film as an action thriller. The fights are plentiful and use a variety of styles – those who think it all a bit samey really aren't paying close enough attention. So many big-budget movies badly fumble the action and edit it into incomprehensibility. The Raid, by contrast, gets down and dirty and focuses on doing it all correctly – it's one long good bit. DVD & Blu-ray, Momentum Community Season 2 The sitcom format is brilliantly destroyed to include chaos theory, paintballing, zombie movies and much more. DVD, Sony Lady Snowblood 1 & 2 Classic stylish and bloody 1973 martial arts revenge thrillers, a huge influence on Tarantino's Kill Bill. DVD & Blu-ray, Arrow My Way South Korea's most expensive movie, a spectacular second world war tale tale. DVD & Blu-ray, Universal The Cabin In The Woods Starts off like a regular horror film, then … well you'll just have to see this audacious, entertaining Joss Whedon-scripted horror deconstruction. DVD & Blu-ray, Lionsgate
