Alpha doesn't have anything to do with the original story, and threw out of the window the themes about society, technology, and humankind, from Appleseed. It's basically an action flick. I do think it has a better dynamic between Deunan and Briareos, but the whole plot and characters are pretty basic - Deuman design got pretty dumb too, using a tactical gear the protects her back and shoulder, but has a huge cleavage just to show boobs. I find this kind of fan service is quite pathetic. What really impressed me is the CGI, it's quite an eye candy. This movie has fantastic looks and it kindacompensates for all the rest.
I'd give it a 7.5, but since I can't, it's an 8.
