Yes, All american voice-actors are garbage. Well, what I mean is. The scripts in the dubbed versions have to be good and coupled with a notably good voice-actor. But anime as a whole (even my absolute favorite DBZ) has horrible acting. It's so over dramatized that it's bad. Lot of the same stuff. "HUH!", Stuttering when something earth shattering happens, growling, screaming when a character is 3 feet away. Just all in all, I prefer manga to anime. Always have, always will. But I digress. (If you'd like to touch on this more, please VM)
Yes, Iris' american voice-actors is what I was talking about. I don't watch subbed so I wouldn't know.
