In my opinion yes it is a poor interpretation of the original, but the people dubbing it are doing the best they can. I mean if they did it just like the japanese version it wouldn't be suitable for the age group they want to make Naruto open to. So technically yes it is poor, but at least give the people credit for it. . . because not everyone has seen the un-dubbed version and some people like the english version better. You can't hate people for that just because they're standing up for what they like.
And on another topic,
IF YOU DON'T LIKE THE DUBBED VERSION DON'T WATCH THE STUPID THING!!!
geez. . . it pisses me off how many times I have to repeat myself about that. . .
