I'll do the seasons :-)
S2 -- both Lorelai and Rory at their best, and very little exposure to annoying characters
S3 -- Pinnochio always makes me cry so hard. Many good episodes, no really crappy ones
S4 -- I love to see Lorelai archive her her dream, and I love to see Rory struggle with college. And yes, I'm a JJ, so, it's kinda obvious.
S5 -- Loved it up to Pulp Friction, even the whole thing with Rory's Logan struggles. I wish I could erase the last 5 episodes, though, especially Kropogs (I felt so badly for Lorelai at the FND from hell) and BIAG (because Rory actually said it)
S1 -- while I fell in love with the show during s1, it was only because I fell in love with Rory (and Lane). Lorelai annoys the hell out of me a lot in s1, and that's hard for me to watch, because she's my favorite character.
S7 -- while I hate seeing Lorelai with Chris, I was relieved to see the girls together again. Plus, s6 doormat Lorelai (caused by Rory, then Luke) makes me want to cry.
S6 -- 'nuff said
