I wouldn't see anything wrong with their taking five years to complete their dub....if they were using that time to turn out something good. The original dub was rushed and definitely would have benefited from more time for continuity checking the scripts, giving the actors more time to prepare and do more than 1 or 2 takes, and editing the episodes, but even being as rushed as it was, it still managed to have charm. The Viz dub has had all the time in the world, and yet it's almost entirely lifeless and much of the (mispronunciation-laden) dialog sounds like it's fresh out of Google Translate.
