I liked it a bit more on second watch. The visual effects are way better than I remember. I dunno if I just took against those big eyes.
I think another factor is that now I have seen Rotoscoped Rosa Salazar (in Undone) I can see her performance in Alita, and somehow that elevates it for me. Like you can see the Andy Serkis in Gollum (right?) You appreciate what the actor is doing under the CGI that bit more.
The script clangs a bit in places and I can, in no way buy Waltz and that massive hammer.
I kind of would have liked to see the second part now. Shame.
