Doesnt quite look like the 1960s
Is it like whenever Hollywood is making a movie set in the 1960s aimed at a teen audience, it still looks like the modern day (as in anytime between the late 90s and 2013), in terms of styling? X Men First Class also had this problem.
I may not have been alive in the 60s, but other modern shows and movies set in that period at least go for authenticity and are a good indicator for what it must have been like. Mad Men certainly submerses you into the 60s feel with intricate details and even the new Star Trek 'reboot', in order to maintain continuity with the original TV show, still has a late 60s feel in terms of styling.
Based on the trailer, the only obvious thing that says that Love and Honor is in the 60s is the Vietnam war reference. Maybe the movie is better.
