I've never been a huge fan of Pretty Cure, but for some reason Yes! Pretty Cure 5 seems like it may be interesting. I bring this up because the only reason I ever watched Nanoha was so I could watch StrikerS, and I was pleased with StrikerS. Basically, watching something later instead of what preceeds it.

Also, I can't seem to find any groups who have subbed it completley, only a tiny number of eps here and there.
