it sucks ass, the american version that is
my little brother was browsing through channels last night and we happened to see it

after several minutes of watching, i decided to put on the fansubbed version to compare them side-by-side
man did they fudge up a lot of the script and also most of the fighting scenes were cut off, how shitty

some of the voice overs were decent, but i really hated luffys, it sounded like crap to me

japanese subbed version is way better
