I thought the movies were overrated (even though 3 is one of my favorite movies of my youth ) but after being dragged to see 6 , I'm a huge fan of the franchise.
In the first two they're trailer park trash and the direction is the typical stupid movie with a hot cast that didn't make any sense that plagued the late 90s and early 2000s.
Since 4, the direction of the franchise completely changed . It's well written , has character development, the chemistry is amazing and the special effects and action scenes are out of this world.
A lot of fans will be really disappointed with current plans . Especially the ones who've rode Earthquake/Disaster before. That was the perfect ride to retheme to F&F and make it better.
