Lots of great dialogue in the movie and I think it will stick around for years to come. Here are some I find myself playing back:

"Han Solo. I've been waiting for this day for a long time."

"Goodness! Han Solo! It is I C-3PO. You probably didn't recognize me because of the red arm..." (I love the annoyed expression Han gives Threepio. Took me right back to ESB)

"You need a pilot..." "...I need a pilot."

"Show me, grandfather, and I will finish what you started."

"What did you do when you were stationed here?" "Sanitation." "SANITATION!"

"Solo, we'll figure it out. We'll use the Force!" "That's not how the Force works!"

"You need to hide."
"You need to leave."

"I'm waiting for my family. They'll be back. Someday..."

That line Daisey Ridley delivered, along with her facial expression, was an outstanding bit of acting and a real highlight of the film for me. Gives tremendous insight into Rey's character with just one line.

And of course, who could forget:

"..." - Luke Skywalker

"Traitor!"

One of my fav lines was during Kylo Rens conversation with Lor San Tekka:

"I'll show you the dark side"

Great delivery

"Oh, really, you're cold?"

One of the few moments that actually was funny. Ford has such a great way of delivering these simple lines...

Agree with "that's not how the Force works!"

My favorite line in the whole thing is "It's just us now. Han Solo can't save you." It works for many different reasons.

Poe's "who talks first" is up there for me as well. As soon as he uttered that line, I had a good feeling about the film.

Kylo Ren is so very quotable! I find myself mouthing all of his dialogue when watching the film. My favorites:

"I'm impressed. No one has been able to get out of you what you did with the map."

"At night, desperate to sleep... you imagine an ocean. I see it -- I see the island..."

"Brin'm'n'Bboard" is pretty fun too

"Where's my boyfriend? I like that Wookiee."

I have to say that I thought the dialogue was not that rememberable... although it may start to stick in the mind after a year or so (the others have had over 10 years)...

"That lightsaber...it belongs to me!"

The first time I watched it I wondered if Ren would somehow try to steal Luke's saber from Rey/Finn. A moment later he sprouts this line..
