I'm definitely interested in checking out Shin Kamen Rider whenever it comes out. Whatever happened to Shin Ultraman, anyway? *goes to look it up* Oh...it comes out TODAY in Japan. Well, I guess reviews will probably come trickling in, at some point.
As for Sentai robots. I think part of the problem is that they're trying to sell SO MANY little toys, that the combined robot itself doesn't really look all that appealing, anymore. *gets out his cane and spectacles* Back in MY day, the combined robot was the main focus, not all the little doo-dads and secondary and tertiary robots, all sold separately. (I'll admit, there are exceptions to this). I can see more poseability being appealing, though.
