Personally, I would rather see a release of "Gridman" (the Japanese "tokusatsu" show that "Superhuman Samurai..." is based off of). However, if both versions were released, either by Shout Factory or some other company, then I would get both if only for the sake of comparison.

Incidentally, it's funny you should mention Ultraman. The original Japanese show was made by Tsuburaya, the same people who make the Ultraman shows.

Yeah, I would love to see that one on DVD.  From what I remember, it was downright hilarious. 

And I also never knew there was a message board here either.  I'll have to tell people about it.
