I've noticed a disgusting number of people who trash Western releases of anime for no good reason. Yeah, a lot of anime gets terrible dubbing but there are plenty that are done very well and sometimes even much better than the Japanese original.
Thing that bugs me, is that Viz didn't have much to work with for their release, and from the looks of things, neither did Toei. So they took their DVD master that Toei made from betas, upres'ed them and tried to filter it so it didn't look like dog. The end result is something pretty decent and almost in line with most current cartoon restorations. Is it as nice as something like Ranma? No, but that company had the film reels to work with. Not sure what the DVD portion of the discs are like though. Those might have been scrubbed clean, and if they were I'd be disappointed with. The Blurays though; are as good as we'll get.
