I felt this way after watching the final episode of Higurashi's first season, then I watched the second season and was very happy. and then the site I visit to watch anime would load the OVA so I felt really angry, but then miraculously it began working about a month later and now I feel like it ended in the best way it could have... And that is to say, with a joke arc.
Another one that gave me this was Rosario + vampire. Don't look at me like that, hell, I don't even know why but whatever, what's over is over, and it's not like I can't rewatch anything I want to anyway *goes to rewatch higurashi)
