I don't think the series has a bad movie. All 4 are great.
I may like IJ4 but I can understand some folks gripes with it.
I don't hate Rocky 5, but I understand why some see it as weaker.
This saga doesn't have a Tokyo Drift as I see it.
There isn't a Rambo 3 for this series.
All 4 DH films to date are awesome cinema experiences and I look for the newest one to stay on track!!!
