Not only the narrative, but as mentioned, the visuals in the first OAV are really impressive. The more I watch it (went through a 2nd watch through with my lil sister) the colours and detail are nothing like I've seen in animes before or since.Animes before seem a little bit dated (such as the first Tenchi Muyo series made previously), but everything after it (including the 2nd OAV) has slightly more faded colours and characters are less detailed. There's something unique in this first OAV. So vibrant and feels a bit more organic.
sadly, El Hazard is all but forgotten about here, naturally.
I actually saw a bunch of laserdiscs of the 2nd series for sale for just a couple of hundred yen (something like £5.00), and I was tempted to by them for the nostalgia factor, but I don't even have a laserdisc player, nor the room to have held onto it.
I'm going to watch the entire first series again now, the first time in years. Really excited to see how it holds up.
That would be a good thing, but I think you mean it has been forgotten due to the huge variety of new Anime that comes out, right? Also I would imagine that the popular Anime genres and styles changed in the last decade, and El-Hazard doesn't fit those anymore.
