*cue all the horrible gaffers saying the movies aren't about cars anymore and how the first film is the best one and how 2 fast 2 furious is better than tokyo drift*
That's certainly true about the 5th film which I thought was terrible but the 6th film definitely had cars in it and it was a blast to watch, probably the 3rd best film in the franchise.
It really is going to be an incredible feat for them to make this film work without Walker. Will it be bookended with funeral scenes? Is this the dark middle chapter of the Fast and Furious saga? (Yes. These films WILL hit #13.)
