Overall it's a pretty good set, as for looks it's pretty accurate to the movie although you can't move much of it. However it does have some good features.
1: the base is easily removable, and although it is barely connected to the Bowie it does stay in quite well. However during the build process when I tested it for the first time I thought it leaned forward too much so I adjusted it slightly. (Because of the technic pieces this was Rather easy) however by the end of the build process I realized Lego knew what they were doing when they specified the angle of the base, because when I set it down I noticed the bottom ring was touching the ground.
2: hopefully this one isn't as long as the last one. Just like that one scene from GotG 3, you can disconnect the sides of the ship to work as separate fighters, however you cannot disconnect the rings from the main body of the ship. However I understand this decision since you can only do so much with Lego.
3: you can move several parts of the ship, such as the rockets on the back, several panels on the sides of the rings, a hatch on the bottom, and the windshield/cockpit depending on what you call it.
Although those 3 features are good, that doesn't mean the set doesn't have problems.
