I watched it recently up to date and enjoyed it. It has some silly stuff and battles are mediocre, but there are some funny humour and characters are likeable. Some touchy scenes too, which managed to get me, as I am wuss like that. It gets better when it process and characters gets familiar when you immerse with story and world, as often is with this kind of long series.
One thing I liked it too was my first impression that it seemed carry story faster forward thansomeotherpopularlonganimeswhichnamesIdarenottomentioninfearofbeingpointedandlaughtedbymoreelitistanimeenthusiastics, without dwelling in single scene too long. Although at this point it has reached manga and I'm bit unsure can it keep its level, but it's more like anime which relies to characters than exciting story, so fillers can be funny too. But there's over 100 episodes to be watched before that, so no worries.
