I saw the in cinema trailer Gintama 銀魂 (2017) and so saw it. I never saw the comic or animation of it before. As usual, if the Japan comics work, follow with animation and then movie version will come out. The story where alien and human live together, and lot of character in the movie.
Usually for great comic or animation, adaption to movie either good or bad, due to different art and visual presentation element different.
For me, overall weak storyline, or maybe due to I do not saw the comic and animation before, so I can not involved in this fantasy world. Some character is really eye catching in term of design and presentment.
