Are the Megaman DS games any good?

I'm itching for some megaman action. Are they worth it?

Megaman Starforce : if you enjoyed megaman battle network on the GBA yep
Megaman ZX : if you enjoy megaman x yep

They gotta make more like the ones from the NES days. I'm not really into the new stuff like the X series or anything beyond it.

The ZX games are a serious step down from the Zero games, and while I haven't played the StarForce ones, they look like crap. I can't believe Capcom managed to take two good formulas, put them on superior hardware, and make both of them worse. Fucking unbelievable.
