You can walk through and really experience Galaxy's Edge in a 1/2 day. My opinion is that TWDC made an earnest effort to theme the land into a real Star Wars experience for guests. In some ways, TWDC was very successful. The ships, buildings, doors, and elements feel like a Star Wars village. The problem, for me personally, with GE is that there is far too little energy in the land. The ships, such as the Falcon or an A-wing are really cool to see, but they just are there. There is no energy around it. Nothing moves. Sounds are muted. There's no life. Compare GE to Fantasyland, I would much prefer to spend more time in Fantasyland because there are canal boats floating, carousel spinning, the beautiful castle, characters walking through, etc. It has an energy that GE lacks.
Nonetheless, I would encourage anyone who hasn't seen GE and is interested to go see it. TWDC did a nice job. Not a great job, but a nice job.
