I just got back from Alita: Battle Angel, and I must say, f*ck the critics, that was a stellar final showing from Fox as a standalone studio. Robert Rodriguez and James Cameron made sure they really went out with a bang before being acquired by Disney (officially). The CGI, character development and action was off the charts. It IS a little exposition heavy, though, I must warn you in advance for those fixing to go see it.
I never read the manga, so I can't draw any comparisons to the source material, but if you like Marvel and/or CGI movies, you'll enjoy this.
