I watched the movie having no idea what it really was or what the anime even was. In fact, I've never seen an anime besides the Dragon Ball series when I was a kid. The plot was interesting, but the overall execution felt really weak. The love story was obnoxious, and, again, we had a movie where certain plot points were reached by extremely unrealistic decision making.
With all that said, it got me to watch the anime, and now, I'm seemingly into anime. I've downloaded Sword Art online, dothacksign, and a few others to get started. So I appreciate the movie, just didn't necessarily like it.
