It seems your main gripe is that there hasn't been a new console Pokemon RPG since XD: Gale of Darkness. While I myself would enjoy a sequel to XD: Gale of Darkness, it's no reason to call games like Battle Revolution and Pokemon Channel crap.
Different strokes for different folks if you will. I can't really speak on Pokemon Channel's behalf but Battle Revolution does its job well. It shows your Pokemon from the DS games in full 3D, lets you challenge different Colosseums and rewards you with items and Pokemon for the DS game, and it lets you battle online with others who enjoy battling.
Also, a bit of a rule of thumb, any gaming series that has a huge fan base is going to tread new waters in the form of lore or playstyles that aren't necessarily accommodating to traditional fans.
Pixel Art can be fun.
