As Arrow is releasing Audition on UHD this June, hopefully other Miike's heyday films are not far behind! Radiance's Underworld Chronicles box looks like a great set, as those 90s V-Cinema and early 2000s productions are arguably the most interesting periods. His output became very uninteresting around the time Gozu was released, 2004 and 2005. Same thing happened to Kitano and Tsukamoto. I'm not sure what was going on at the time, but it's as if they all ran out of steam and good ideas. I tried some later day Miikes, Shield of Straw and Blade of the Immortal, but they felt like a waste of time. Maybe I should give a change to Over Your Dead Body.
This doesn't include Miike, but V-Cinema Essentials box I can recommend. Many entertaining crime and action films that were buried to obscurity outside Japan, until now. And how about Gaira's Guts trilogy on Blu-ray, fucking amazing that they were finally released! Other gory direct-to-video productions are also finding their ways to Blu-ray. Jōji Iida's Cyclops (1987) for example. The mutation effects are on par with the Cronenberg stuff of that era.
