These movies are so cool.
For me Lake was the strongest of the bunch but all three have a wonderfully spooky stylish look and feel to them. Makes me curious as to what a Michio Yamamoto Godzilla film would be like, I imagine something like a cross between Hedorah and Terror of Mechagodzilla.
Godzilla fans should recognize quite a few faces as well - In Vampire Doll Sachio Sakai (Hagiwara in the original Godzilla and a bit player in many other Honda sci-fi films) cameos as a cab driver, and a young Akira Nakao (Commander Aso in the Heisei series and Prime Minister in the Kiryu films) stars as the male protagonist. Shin Kishida (the Interpol agent in Godzilla vs. Mechagodzilla) appears as the main vampire in the last two films, and he's one of the coolest screen vampires I've ever seen.
Only thing that really bothered me, and I hope I was seeing things, but I'm pretty sure there's some animal violence in the first film, where it appears a crow gets its throat slit. It goes by fast but it should go without saying that is appalling and unnecessary... there's also a pretty convincing dead dog in the second film, but I like to think that was a well done prop.
