Hearing "AW FUGK THEM DAMN USRAMRIKANS R SCRIWIN WIT MAH FAVRITTE ANEMEY11!" is really annoying, especially when they hardly ever change the anime or any other Japanese show.

Example 1: Ringu and The Ring.
I've seen both and I think they're equal? Why? Because they're the same damn movie. I found very many similar lines in both movies. Everything, save of course for the actors, the setting, and the music, is the same. I, however, found the US version of Samara to be scarier.

Example 2: Dragonball Z
I can't think of a better example. For years, people have complained "BLAST U AMRIKANS MESSN WIT OWR DRAGINBAWL!1!". They editted out male nudity scenes and some blood. Otherwise, Funimation stayed true to the story and the voice actors were decent and tolerable. Or would you guys out there prefer to see penises and hear a Japanese man with a high-pitched voice scream at the top of his lungs?

Bottom line, the US does a fine job with its anime transitions and movie remakes. Just look at FMA, Inu-yasha(though it has a terrible script), and the soon to be Get-Backers.
