Nope. You can easily find subtitles for literally anything on the internet. Some players even download them automatically. "Pirates" in the anime community pretty much invented this subtitling technology. You bet this data is included, either in the container file or as separate subtitle files.

Meanwhile HBO lacks english closed captioning for most of its content. They give me subtitles for spanish sometimes even though it's not my native language. Not to mention the obnoxious censorship and inaccurate translations.
