PURE is the only thing worth watching in my opinion.
Subtitles are lame for several reasons...
1: they detract from the action and the voices, so that someone reading subtitles is not even listening to the words. This detracts from the art of the cartoon, because a great deal of the art is in the voices and acting and the actual ART! Watch the show not the subitles!
2: because this show has never been 'officially' translated, all subititles are made by unprofessionals and most of them are actually just translated from chinese translations of the original japanese, making them two times removed from the original words. In other words, I have never come across a decent subtitled movie or episode EVER except for mizu no miyako no mamorigami.
3: They are irritating and rarely correct. If you don't understand japanese jokes, cultural comments, puns, caricatures, &c, you will not understand a lot of this show. There is no way to translate these things into another language, just as a lot of English humour would have a terrible time translating into Japanese.
So in my opinion thats the final word on it. I hate subtitles! They're horrible! Why doesn't somebody who actually speaks Japanese make them! THey're distracting and poorly translated and detract from the show! Do away with them forever!
