Could someone please just respond to the following statement without going on some ridiculous tirade?
Why do you feel the need to go after TV-Nihon at all? Why not just move on and watch Toku wherever you want? And if TVN is the group someone starts with why not just be glad that our fandom is growing and let that be that? Why do you give a **** about what fansub group people are watching? Does it really matter?
When the subs have inaccuracies or stylistic choices that affects the way people will interpret the work, yes, it matters. There's a large audience of people out there who have no clue what Kamen Rider Blade is about, that matters. There's a large audience of people out there who will have a twisted view of Gotou's character arc in OOO, and that matters. There are a large number of people who, because TVN do not attempt to make jokes in the source language actually funny in the target language, have deluded themselves that tokusatsu as a medium "doesn't do" humor and will attempt to argue against the very nature of the franchise, and that matters.
Someone watching a fansub that doesn't do the work justice doesn't just affect them, it affects people around them. They might recommend that translation to others - and those people will be ill-served by it, their opinions formed from inaccurate or ill-fitting interpretations of the work will come up in conversation and may skew how others see the show. These things are a connected web, and a translation that doesn't do a show justice permeates down into the social conscious of said show, and affects how it is perceived.
So yes, I think that matters.
Edit: Okay, lemme elucidate a bit.
As a fansubber, I do what I do for two reasons. The biggest one is, I enjoy translating. It's fun, challenging and thought-provoking to me. But you know, I could just translate what-the-**** ever and sit on it and purely do it for myself if that was the only draw. But I choose to work on tokusatsu that gets released to people because I enjoy the shows, I enjoy the medium, and I want other people to enjoy them too. I've spent time learning a language so I can watch a TV show, play a game, listen to a song, and experience something. I can understand what its saying, understand the message it has, be moved in the way it wants me to be moved. And it's like, if I put out a translation that doesn't allow people to have the same reactions, well, why the hell am I bothering?
This is, to my mind, the really big issue with TV-N's subs. On the whole, they're very utilitarian. When you treat the Japanese language - both in general and the specific words used - with more reverence than the meaning and spirit of the work itself, problems happen. Jokes stop being funny, twists may lose their impact, the viewer's ability to just switch off their mind and enjoy the show is severely hampered.
Here's a flipside example: Go watch KouAidou's translations of The Hero Yoshihiko. That is a show full of Japanese language jokes, Japanese cultural references, Japanese celebrity jokes. But you could look at those scripts on their own and be totally unaware that what you were reading was even a translation. It's a translation that entirely serves the point of the work, the humor of the work, through localizations so witty that they become invisible even to a translator. And that, IMO, is the crux of what good translation is: invisible. Nothing in a translation should ever make you stop and consider it, should make you query it while you're watching, should make you take your focus and attention away from what you're there for: the show.
If you want to learn language and culture, that's admirable. And there's probably people who learned a lot through watching TV-N's subs (though there's enough mistakes in their work, especially their older work, that it should definitely not be your primary linguistic intake). But ultimately, a translation of a work should always exist to serve one master and one master alone: the work itself. Language is a beautiful thing, but in this case it is a tool, a canvas, and not an end unto itself.
