Goemon looks just exactly Casshern now, Kazuaki Kiriya is well on his way to becoming the Frank Miller of Japan. The overly grimdark style and shaky plot of Casshern was decent I'll give you that but its something that shouldn't really be done if you can't put together a decent story. Now he's pretty much took Goemon, applied everything that was Casshern into this, copy paste, repeat. Casshern clone much. Kind of like what Frank Miller attempted to pull of with the Spirit (ala using Sin City).
Two big name toku related movies released relatively close to one another?
I'm honestly not too interested in this movie, I want it to be good because it's damn pleasing, at least aesthetically, but it took me three viewings before I could actually get through Casshern. That movie was just one big mess of unintelligible eye candy.
Yatterman definitely looks like the better movie, something that won't take itself too seriously and knows how to have fun.
Monkey Punch also got sued by the original creator of Lupin for copy right infringement but I think the copyright had expired and Monkey Punch got off.
