Slayers, thankfully, wasn't such a big disappointment, but it wasn't exactly how i hoped it to be. but i guess, it's still too early to judge. i remember in the older series it got more interesting in the middle.
haven't seen the older version of it, but Birdy was pretty good. though, i fear this'd may end up like most anime that starts out good; they turn not as quite as good as the first ep. with only 13 episodes, it better be done right.
