The matrix is a groundbreaking film by many standards. It was one of the first films to use super slow motion and explore some ides and subject not yet done in modern cinema. In the film Neo is thrust into a new world like nothing he's used to before.
One of my favorite quotes comes toward the middle of the second act and is almost poetic to me and fits within in the story in such an interesting way. Neo has just been awoken from the matrix and is welcomed in by morpheus and the crew, it's as if he as just been born again. Neo is laying on a table and ask morpheus why his eyes hurt, and he replies that this is the first time he's using them.
All Neo has known at this point is the confines of the theoretical world the matrix has built for him, essentially only seeing an artificial world. This is the beginning of neo's jounrey and everything he sees form this point on is going to be so foreign to him. It's really cool when thinking about the use of Neo's eyes from the first movie connected to the last when he eventually gets blinded. Another interesting take on this quote is how it fits within Platos allegory of the cave which the matrix is essentially based upon. Neo has learned to break free from the darkness as he exits the cave seeking the light.
