I very much enjoyed it. Like many I could do without the overly muddy CGI-fest ending* but, overall, it was very good. It didn't follow what little I remember about the original comic back in the '70s but as with Spider-Man being switched from being bit by a radioactive spider to being fallout from gene splicing experiments, I can roll with it. If it works, I'm good.
Very glad that they didn't make Katy into a throw-away character who ends up hiding under the bed.
* I'm not against heavy use of CGI, but rather when it's used in a way that doesn't allow you to follow the action.
