I love cars, that's what got me into this series in the first place. I've watched Initial D as well.
My opinion : Do you remember the movie "Need for Speed (2014)" ? It is similar in that both featured really nice cars and great racing scenes, but both are very lacking in storywise and dialogues...
Even the racing scenes, albeit cool, are kinda Japanese propaganda in my opinion. Yes, GT-86 is a great car, fun to drive, and I would love to own one, but saying that it is on par with European V8 or V10, is the same as saying that a katana is better than automatic guns...
Yes, the driver skills do count, but unless the 86 is driven by a professional world-class racer and the others are just some high school teens who just got their driving license, it is very hard to believe an entry level sports car with 2.0L 4cyl Boxer can go toe-to-toe with a Huracan or 911 in a speed competition. Even the original Initial D didn't get that far...
