“Tokyo Vice”Thursday, April 7, HBO MaxMichael Mann, the visionary filmmaker behind “Heat” and “The Insider,” returns to television for “Tokyo Vice.” (Yes, Mann was also one of the people behind “Miami Vice.” But there is no connection between the two beyond the title.) Based on the 2009 book of the same name by Jake Adelstein (played in the show by, um, Ansel Elgort), who in 1993 was hired by one of Japan’s largest newspapers to be its first non-Japanese reporter. Adelstein is soon taken under the wing of a veteran vice cop (Ken Watanabe) and exposed to Tokyo’s dangerous underbelly.
