Fans of Hunter X Hunter will recognize the similarity of the hit shonen series to Yu Yu Hakusho. From a slow start where characters are introduced to tournaments where each of the skills were developed, an arc where they need to save humanity and an in depth view to their Ancestry in a different world. Though the storyline seemed so natural from the highlights given, what is special about the anime is on how they manage to keep the viewers excited as each episode ends. I'd say that it's a perfect anime if you want to do a marathon, just don't get discouraged on the slow start of the show as it will pace beautifully as the series progress.
Characters and their development is one of the best thing that you'll notice in the series. I'm quite sure that you'll end up picking your favorite among the four and get enthused by his skills and his/her future development. What made the characters outstanding is not about their similarities or ideology that they follow but because of the chemistry that each one brings despite their differences. Aside from the main casts of the show, the antagonists also helped a lot to streamline the endings of each arc - I think it started from the Dark Tournament are where the villains are more powerful and their back story are starting to get more appealing and relevant to spice up the story a bit.
For those who are very particular about the art and animation may find this one disappointing especially when you're used to watch new animes. There's some irregularities on the art with vivid colors lacking in most part. But still It's not a major flaw of the series and in fact very decent at the time it was being aired.
And lastly the Soundtrack - I think I can still recall those catchy tunes from the opening and ending song of Yu Yu Hakusho and sing without missing a lyrics. Other viewers disagree that the OST is good there's nothing special about it but in my opinion it's one of the best and perfectly fitted to the anime. The only thing that I missed in Yu yu Hakusho is the original voice casts. As I've seen it dubbed in my native language, I think my experience could have been better if our local channels didn't alter the original but still I enjoyed every bit of it.
If you've got nothing to do this summer in the Philippines and haven't seen the show you can do a Marathon of Yu Yu Hakusho, following with another marathon of original Hunter X Hunter and you got yourself an animazing summer vacation. Just make sure that you do it at night and don't get too close to your TV/PC cause your eyes will definitely hurt. I'll be rating the series a great BB+ (Double B) Watch it if you have time!
Before I forget, Yu Yu Hakusho is popularly known as Ghost Fighter here in our Country - and you can spot the show too in GMA7 if you're lucky enough since they mostly recycle anime these days.
