I liked season 3 very much..right up until the terrible ending. I thought season 2 was ok but not great. And i freakin' loved season 1! :)

All except season 4 (so far)

If the rest of season four turns out how I want it, then I would add that, too.

S3 - (Quinndependence, Santana getting out closet, Blaine joining ND, TGP guys, no Finnchel dramas, greats songs, a Michael tribute, Klaine's first time, spotlight for everyting, Mike's development, Samcedes, ND winning nationals, Sebastian Smythe, Brittana happen, and any more...)

S2 - (Blaine, Tike, Samcedes starts, Artie not alone, greats songs, Shannon Beiste)

S1 - The starts of everything!

S4 - (The New Rachel was awesome! and everything about it was!, Britey 2.0 was good, but I didn't really Makeover and I'm not very exited to see my favorites couples breaking up...

I usually say 1 is my favorite (which I'm sticking to). S1 and S2 are like two different shows. S4 is giving me an S2 vibe (which is a good thing). I don't even know what happened to S3 but if bet if we writing quality-wise skipped from S2 to S4 we would not have viewers in the 5 millions right now. S1 I love because of the real underdog feel of it. Everything was so young and fresh and simple.

Everything was perfect in season 2...

I agree with you @Klaine_forever. Everything in season 2 was perfect. I can't choose between one and two. Season 1 had St. Berry though and the most Kinn. <3 I found season3 incredibly boring except for some of the music and very few episodes. But it gave us Sebastian, so I can't complain to much. Season 4 has gone okay so far. But I'm not so happy about the overload of new characters or Brody.

I can't pick I love all the seasons. Tonight's episode is probably going to be the one that gets people the most pissed off though.
