Where can fans of the genre find Japanese Giants? Poor market exposure could be a factor in lower than projected sales. I'd love to check it out, but have never seen it

Indeed, I would all but kill for more stuff on Frankenstein Conquers the World and/or War of the Gargantuas.
I agree with King_Ghidorah, insulting people's tastes and calling them "twerps" isn't likely to endear you, or your opinions about cool kaiju stuff to anyone. Even so, Ebirahsmeg1 you have tremendous knowledge about the subject matter--and related cool stuff!

Helpful advice and plugs for product like Japanese Giants will go much further!
