Ending Season 1

I remember that feeling years ago the ending of season 1, sitting there speechless and feeling empty after.

I wondered if any of you ever experienced something like that in a tv show without mentioning it. People might get spoilerd if you mention a show or episode.

Even after rewatching season 1 i had the same feeling. Season 2 ending was fun and all but the feeling was different. I am looking for season 3, but the excitement is not there.
