You are right Rob Ichi is great, a little confusing but great.
One Japanese horror you might like is Evil Dead Trap it is extreme and freaky.



Just watched Evil Dead Trap
Thank God the sun's coming up, cuz I'd be still checking under beds, in closets with a baseball bat. Lots of great moments, and the ending WTF? Great recommendation. I thought I'd seen it all till the bullet time moment in City of Lost Souls. Man, I need to catch up with this stuff. Also saw the first Dead of Alive and worth picking up, the next two installments will be picked up soon. Smartt mentioned Versus, as well, I'll pick that up too (I think it's a zombie flick). Sorry, this feels like a +1 post. I'll try to return the favor with some good recommendations. I guess just thanks for the recommendations.
