I would have to say Wolf's Rain for sure, it just felt like it was all a waste, just one big circle that went from beginning - adventure - beginning, never an end. I actually heard the writer wanted it that way so that fans couldnt complain and ask him to do another season because the way he did it made it so if he made another season it would be exactly the same as the first. FMA is an obvious one, so many unanswered questions. There is a rediculous amount of anime with unsatisfying endings but even when i know they are that way i cant stay away from them!!!
