I dunno.
I used to love Ah! My Goddess!, but it just gets... repetative. I've got the OAVs, the movie, and 32 episodes of the "mini goddess" series on from a fansubber... I've got 6 volumes of the manga... And really, except for the first issues of the manga where they introduced the characters, it just is the same thing, strip after strip. Oh, there are some unique ones... The Cherry Blossom Spirit one was good, so was the mini-ninja series, at times, but really, it's quite repetative... Skuld being overprotective of Belldandy but ending up helping anyhow, Urd causing trouble just because she's urd, Belldandy being... well... Belldandy, Keiichi getting roped into yet another motorclub project with insane machines... It's like a TV series that ran too long.
Things got sorta fun again when they introduced Peorth, but... well... the new isn't new forever, ya know?
The movie... Well... The movie was like nothing else in the series, that's for sure... It was touching and very well animated and had good music... there are a lot of good things I could say about the movie, actualy... but it didn't really feel like AMG/OMG. Same characters, similar trappings, but vastly different in tone/theme/plot/etc.
Love Hina, at least, has a fairly wide collection of differing plotlines for the different strips/episodes. Sure, it always comes back to the Tokyo-U thing, but while working within that one plotline, they have a lot of variation. And Su is always good for a laugh or ten. (Su seems to have several "cousins" or something in Anime... Su is very similar to Ed in Cowboy Bebop, and she has effectivly a twin sister in Battle Athletes... Tanya, who looks a lot like Su but with longer hair (still same style though), comes from some vaugly defined african/indian area, is semi-barbaric at times, but an idiot savant at others...)
