I think, overall, the Japanese want quality films like GMK and the Gamera Trilogy... a more "serious" look on the genre with great SPX like these films had. GXMG and Tokyo SOS are good quality film too(just imo).
I just think this is what the Japanese want now. They're tired to low budget looking Kaiju films in this day and age. Ultraman does good because the budget for those films are soooo small. A box office flop Godzilla movie makes just a much money as a box office success Ultraman movie. Really.. I don't even know what I'm talking about now... just trying to say that the Japanese want good looking SFX Kaiju films. That still doesn't guarantee success though.
