LotGH is an excellent series - one of the best in existence. But, as Jailbait has highlighted in the past when I've posted about it, it's flaw is that it takes a lot of effort to watch and can be pretty draining. Unlike most lengthy series, LotGH is dialogue heavy and can be rather complex, plus it has more character names and ranks to remember than is good. It's the sort of series I'd need to watch constantly or risk having my interest levels drop.
There's also the fact that, the first 16 or so episodes side, only low quality (in terms of video quality) fansubs are available on the net. Watching an endless series in low quality on my 19" monitor isn't exactly very tempting, especially when I have to sit on my chair because my bed is too far away.

Meh. A pretty boring anime, not helped by the alien elements taking away from what could've been a realistic and involving slice of life series. The first four episodes haven't pulled me in, and I doubt the remainder of the series will be able to make me think of it as being more than a 7/10 watch and forget series. Not what I was hoping for.
