Hausu is a fucking wild ride from start to finish. Love that film.
I think the last ''horror'' movie I watched was Cold Fish by Shion Sono. It's the third film I've seen by this guy, after Himizu and Suicide Club (which were both pretty damn entertaining, though totally different in style and atmosphere) and just like the previous two, this one also goes for a totally different mood. A spineless beta guy whose family basically walks all over him gets involved with a serial killer running a tropical fish store and things go downhill from there. I thought the movie felt pretty damn realistic in the gore department. To be honest, it's been a while since I saw a movie where the gore actually felt somewhat gross, not just entertaining. I mean, I just can't really take excessive gore like in Braindead/Dead Alive or Tokyo Gore Police seriously because at some point it just becomes too cartoonish to really count as nasty in any way, shape or form, but the way in which the violence was presented in this one actually felt somewhat more ''real''.
My biggest gripe with this one is that it goes on just a bit too long for its own good. Definitely some parts here and there that could've been cut out or shortened without any problems.
Anyway, if you like tropical fish, serial killers or spineless japanese dads you should give this one a spin
