everything you were told about japan is true. they even have bugs in vending machines. that was a pretty big trend for awhile,bug collecting i mean. theres even whole stores called buru sera (bloomers,sailors) that has teenage school girls panties with pics of them. also japanese porn does make american porn look tame but they blur the genitals of the performers ,due to obsceneity laws or someshit. japanese animation gets past this by habing bitches fucked by demons and tentacle dick monsters.
if you liked battle royale go get the sequel. i have it but still havent watched it yet. it picks up where the first left off. the 2 kids that made it start an organization to do away with the battle royale act,so takeshis character(yes hes alive) has a new class sent to kill them. as for the plot of the first i think you were right about the age gap thing. to see something inspired by survivor rent the american movie series 7:the survivors. its about a reality show where they randomly select people to participate in a killing game and anybody is eligible. it opens with the reigning champ( a pregant woman) gunning down another contestant in a convenience store and then buying a snack. the plot thickens when one of the other contestants turns out to be an old love. they also threw a teenage girl into the mix. i think she was one of the first to get killed.
if you get the takeshi kitano zatoichi remake, be sure to get the 2 pack that comes with another kitano flick called sonantine. i dont know if i mentioned this before and i dont want to click back because ive been typing for awhile and need a shower.
shit before i go i want to say watch ghost dog(especially since you like rza cuz he did the score and has a small cameo). i saw it for the first time a couple weeks ago and its really good. its very reminiscent of yakuza movies. hes lives his life by the code of the samurai and does hits for a mobster that shot some guys that jumped him when he was a teen. on his most recent hit he leaves behind a witness who was a mob boss daughter or someshit. i dont remember if this pissed other mobsters off cuz of the girl or if the ghostdogs mob connect had the guy killed without it being sanctioned. either way his master(as ghost calls him) is ordered to give him up. its good and you have the option of watching it free of dialogue so you can take in the score(which was released as the soundtrack in japan and we were give some shitty wu affialates and throwaway wu tang tracks).
Sorry for a triple post
Frankie, I'm on the fence in regard to Battle Royal II, but if Longshot (who?), Smartt, and Cleetus says no, then I'll probably just let it sit there. Thanks for the recommendation of series 7, I'll probably check it out, although it's probably no where near Man Bites Dog. That film is fucking CRAZY! Goggle it or rent it if you can. But I'll still check out Series 7, I think Bravo or someone is doing a contemporary "reality" show similar to this one. How strange art becomes reality becomes art once again.
Oh and don't get me started on sonantine or the other film fireworks. Not as exteme as Battle Royal, but still great none-the-less. I've seen Ghost Dog already, thanks though for the recommendation, so many great moments in that film (I hope others reading this and not posting check it out!!!) I could say it all goes back to Kurosawa's Rashomon, as the girlfriend reads that work in Ghost Dog, but I wont. 
Will check out series 7 though, and if anyone hasn't seen it already, Man bites Dog is WORTH checking out. Not a so-so recommendation, but a MUST SEE recommendation.

P.S. Frankie, for what it's worth, you take a lot of shit here on this board. I imagine your in your late teen/ early 20's. (And I don't mean to dis you with any of this as I am in in late 20's) What am I getting at? Well, from my own life (and again I'm not trying to pull some your younger then me "kid" shit, as I always hated hearing that shit when I was young), but just recognize that's a hell of a good age to be. That being said, you take a lot of shit of these boards, yet still get up off the mat. What am I trying to say, well I hope that this same kind of tenacity continues throughout your "regular" life. Again not trying to prevent you from posting on porn bbs or call you out on charges of being of bitch, but you have a drive or a fighting spirit that most people on this board dream of. That being said, choose your battles/wars with great care. Being intelligent is one thing, being tenacious is another (e.g. there are those content with winning the war, yet losing the battle). Keep fighting, but as we all grow older, the more ignorant we become (e.g. as a teenager I thought I knew everything, then as I got older, even though I read GREAT books and saw high-minded films, I got dummer. I don't know if any of this makes sense, just keep the tanacity up whereever you are employeed.
