It was definitely "Kenough" for me. I'm tempted to go and watch it again just because of how good it was. The movie is fun and colourful with important messages all throughout.
I will say it's important to keep an open mind, a friend of mine felt it was very much "anti-man", I think it was more to bring to light what women go through. It's also important to remember that Ken has never been a "main character" with Barbie, not with the dolls and certainly not in the movies, so to have this first taste of what it can be like to feel appreciated, respected, and wanted could turn any simpleton.
