I've always loved Anime, and it's always been frustrating watching Hollywood movies destroy it (Ghost in the shell). Alita however did an amazing job in fusing Hollywood and Anime. I believe it was a great story adaptation by James Cameron, breathtaking action scenes and directing by Rodriguez, and great casting. I saw this in 4DX 3D in Seoul and It was a roller coaster ride. I was afraid the movie might put me to sleep, but it kept me engaged and watching from beginning to end. I think the most important element for movies should be the ability to engage the audience and never let them go until the very end. This movie delivers. And also I am very proud of Director Rodriguez for taking on this enormous task. He put a lot on the line to make this film.
An interesting thing I found was for some reason I felt there were elements of John Carpenter here.
Overall one of the best 3D films made so far. I believe the bar has been pushed higher for all filmmakers. A must watch in 3D exerpience!
