SUBTITLES FTW!!!
I've seen a lot of anime here in the Philippines dubbed in the local languauge, and they pretty much suck. As for dubs in the American language, the only anime I recall that had for me IMHO had good dubbing was Samurai-X a.ka. Rurouni Kenshin.
IIRC, the American dub of RT was shown here locally once and I did not like it. Although I did eventually find SDFM through my research in the Internetz about RT.
