Recommended Anime live action : Gintama [ 14 July 2017 ]

The reason why Japanese keep making Anime live action using Asian cast and not western cast is not because of budged, language or other issue like that but simply because Japanese don't find westerners attractive

Anime characters are based on Asians including with Anime characters who have yellow hair and blue eyes because Asians facial & body form is what Japanese find attractive

So far this is the only Anime live action who stay true to the Anime or original source so this could be the best Anime live action in 2017, you can easily see that from the characters hair colors.
