Is this really any different than a reviewer not listening to the Japanese language track? I think it's a shame that Jacob doesn't want to give the dub a chance, but it's his preference.
That said, I don't think people would be getting so upset if Jacob didn't list the dub as an "extra". That's not an extra, that's the default audio track and is part of the main presentation. And just for the sake of argument, even if you DO believe it's an extra, it deserves at least a bit more detail than just listing it. If I wanted a mere list of special features, I could look it up on Right Stuf.
