I was pretty disappointed overall. Mostly by how weak the dialogue was. Too many jokes didn't work for me, and the few that worked were often repeated way too much. I also didn't like how dim Luke was throughout the episode.
Lorelai is still quite immature, which isn't a surprise, but even by her standards she was pretty terrible here. She had sufficient time to come up with a nice story about Richard. Yes, their relationship was strained, and he was too busy throughout her childhood, but it's not like they never had nice moments together.
Frankly, I couldn't care less about Rory's love life so it was a bit of a relief it didn't get much attention so far. She is still selfish, irresponsible and spoiled just like she was in the latter seasons and yet everyone is treating her like a princess so nothing new there.
