91 Days: A Punchy Short Gangster Movie

I could see 91 Days as a punchy, short gangster movie though. And I think this would be a much better movie experience than a series because so much of the series was making this really complex mystery play out that had a very simple solution. Because there are several anime that just would not work as a movie. But especially shows that are like, that have that driving plot line and have a concrete end, those are the anime that could become movies.
