No you haven't, CK. I think the only thing you've made perfectly clear is how little you know what you're talking about. The special we're discussing and the special that you linked are two completely different things, regardless of how convinced you are that they're the same. The special you linked shows how Bardock discovered Frieza's plot to blow up planet Vegeta, and him getting "obliterated" by Frieza's blast. The one that this thread focuses on shows that Bardock was never obliterated by the blast, but instead sent back to the past. In this special, we find out the Legendary Super Saiyan was actually Bardock.
These specials are completely different. They reveal completely different things. I have no idea how you are saying they're the same thing, as if you actually knew what they were. You'd have been able to figure that out if you'd read plot synopses, let alone if you had watched the special, neither of which I'm sure you bothered to do.
If you had even bothered to watch the specials, then you would find that most of them are actually really enjoyable, like this one. If you had bothered to even WATCH THE SERIES, then you would know that your uninformed and rather aggressive opinions of it are absolute crap. You're too scared to watch one of the most defining anime series of all time? In case it's crap?
Furthermore, KotW and his posted image are absolutely spot on. The Japanese voice acting is legitimately shit when compared to its dub. Contrary to popular belief, exceptions to the standard "JAPANESE WITH SUBS ARE ALWAYS BETTER" actually exist, such as in DBZ or Yu Yu Hakusho. Which you would have known if you had watched the series.
Likewise, you should also know that this special does not in fact revive a character from the dead. It's the reason it's a special. While I don't necessarily agree that this special was necessary, it was only reviving up old plot points and trying to explain their origins. It's pretty good actually, and I honestly really like how that turned out.
But I have an idea. How about you watch Dragon Ball Z before generalizing it. You would find out that Dragon Ball Z is definitely an exception to most anime. It's amazing.
So before we decide to make broad generalizations about a show we've never watched...let's fucking watch it, shall we? That way you sound like less of an ass!
