ALICE is, as others have said, not a good film. The 3D graphics are the least of its problems - not good by any means, and in fact a notable limitation for any scenes trying to communicate personal emotion compared to zooming hovercrafts, but still visually the film has a kitschy charm. What lacks charm is the story that is completely adrift - it presents a gonzo sci-fi time travel plot with none of the gravitas that story needs, paper-thin characters supporting it, and a healthy dose of out-of-place fanservice hijinks as icing on that cake. The entire thing comes off as an amateur executionof a derivative story concept by creatives who had to checklist plot points to get the thing out the door.

Still, while being a bad movie I think some people might appreciate it as a unique piece of art. Not because it was the "first" computer animated anime film, that is just a checkbox, but because of what that meant in practice. People like director Kenichi Maejima were very excited about the changing technology at the time; they wanted to push it further than others had gone. And the technology, that of making a "world in the computer", fit thematically into the edgy, sci-fi, apocalyptic aesthetics of the movie. The film is VERY 90s, in a way that was derivative then but today is fun to see as a symbolic stand-in; you can see how this is like some extended Final Fantasy VII riff by the creators. They had very few rules for how this technology and the ideas of the film would come together, and so seeing their mistakes and very occasional successes is quite fun. If you want to see creatives try-and-fail in a time that is now gone, you might enjoy ALICE.
