Yeah, I can definitely see that you put a lot of effort into working on this review, which is why I said that it was great (and trust me, I'm not just saying that for the sake of it ).
Its just that I'm sure that "they" would have been even better as 2 reviews which were not corabined into 1, or rather, the way that you originally wrote and intended the reviews to be.
Well, it is unpopular among both older and newer generation anime fans, but for the generation which I like to call the "Toonami Generation," its extremely popular. Overall, though, with a lot of good anime being almost unknown to many fans, I'd say that Yu Yu Hakusho IS indeed a very popular series, especially in name. Its just that most other sites give it more negative-to-"average" reception in their reviews, so its nice to see that you gave the show a completely positive review, which didn't seem biased at all, IMO.
As for Avaitor saying that he's glad that the TZ staff knows its existence, I don't think that he was saying that its generally unpopular, but that (at least from both his knowledge and mine), this is the first time that we have seen a review for this show on the site, which is something that I had personally really wanted to see ever since I joined TZ, and started reading the reviews posted here.
