I really want to watch this series, but a friend (amongst other various users on the interweb) tells me the ending isn't very satisfying. I have seen the first episode and the show definately has potential, but I don't want to pay for and waste time watching the whole series and find a mediocre, inconclusive ending. No spoilers please, no need for a description of the ending or anything, I just want to know if it left a bad taste in your mouth... so to speak.

Also, is there an OVA, movie or even sequal in the works as of this moment? That would make a crummy ending slightly more bareable.
