Gintama

If you have any concerns with this adaptation, don't worry I originally was concerned too, until I watched the parfait scene at the beginning, then I realized Gintama was in good hands here. The movie is literally just the anime but live action. The characters could be accurately described as their animated counterparts. I think Gintama is the only manga series to be translated into real world this easily because of its fourth wall breaking and anime parodies. Truly an amazing movie.
