My first reaction was in my topic from last night about the advertising being too much "battle" and not enough "angel." The marketing really failed this movie... I'm glad I didn't expect it to be like this, because it was a surprise, but the movie being so sweet and endearing and beautiful is something that should have been pushed, because it would really put butts in seats.
I could put together a "beauty" trailer demonstrating it as a visual work of art, plus highlighting the touching, heartfelt family drama that dominates the story. It would look like a completely different movie from the ads and trailers I've seen.
The worst part about advertising the action scenes so hard is that these are visually stylized ballet-like action scenes that don't really come across in short clips, they have to be taken in as individual extended sequences... Even the violence and "kill scenes" are glorious because they show a beautiful indulgence in the destruction, something that is part of Alita's nature and which drives her to combat evil.
Beyond that, they can't be taken out of context, as EACH action scene is a specific, emotional step in Alita's development. They are her growing pains.
