I haven't read the novel but I finished the drama and like most of the times in the movie can't be shown everything so it felt a little bit rushed. They have made some differences in the movie, like Cao Guang being the same person with Zhen Shui Wu Xiang (the ex of Wei Wei in the game) but is well connected. I liked more Wei Wei played by Angela Baby, she portrayed more effectively her emotions and feelings. Jing Boran hasn't the charm of Yang Yang (main actor of the drama) but he played very well the role of Xiao Nai and I liked that Xiao Nai was more talkative and smiled more often in the movie. :D ;) The scenes inside the game were amazing, it made you feel like you were playing the game together with them. Especially the battle with the dragon in the game was awesome. Its perfect movie especially if you are an online game fan :P ;) its modern, romantic and sweet without any dramas and it focus more on the online game world.
