What is simply not the case is thinking that rooted hair can look good if it comes from Hot Toys, it hardly ever does. I'd say Scarlet Witch is the only exception, more or less, because mine turned out good and it looks better than most of the other ones I've seen.
And when I say it looks good it's only because it didn't suffer from the Barbie frizzy-poofy shit that usually happens to rooted hair. On mine its closer to the head and falls more naturally but even then it's not that great.
It's obvious that with those moving eyes Alita needed sculpted hair. Her hair would look like a mess after changing her eye position a couple of times, there is no way around it.
