....but then again I've been weening anime for a 
while recently.  Though, I'm sure you know that 
I would say ANY ENGLISH DUB is bad.  I will rat 
on any and all dubs for as long as people refuse 
to act more realistically and as well as those 
in the originals put their hearts and souls into 
what they do.  They MAKE you believe that the 
characters are real...whereas the English 
ones... they're simply reading black words on a 
white piece of paper.  Though, some dubs are 
better than others, I still would never trade an 
original Japanese audio anime or game for a 
piece of crap English dub, of any quality.  

But besides that, one HORRIBLE anime comes to 
mind, and I only watched it because it had the 
same "theme" as an RPG that I enjoyed:

Suikoden: Demon Century (I believe that's the 
subtitle for it).  It's been AGES since I've 
seen this, but I just remember feeling ill 
watching it.  Avoid this one at all costs.  (I 
watched the subtitled one, too... so it's the 
story that's bad...)  Those of you who are 
familiar with the basic story in the Suikoden 
games, there are a total of 108 stars of destiny 
that are supposed to gather to save the 
country/world or whatever...  I really wondered 
how they could use the same myth or whatever for 
an anime movie.... and it's easy to say 
that...they really didn't.  haha  I think they 
did meantion the Stars of Destiny thing, but... 
only 6 or so of them appear.........  So go 
figure.  The crossdressing chara was the only 
comic relief in the whole thing.
