They both are the top 2 of the franchise no doubt about that.

I'm going to have to go to the original one.

The muscle cars in the 4th just took the cake for me.

I'm going with the original. Both are great movies but the original had more racing in it.

This last one was just lame, plain and simple.

IThe last installment was the greatest, lot more twist and turns, more action scenes and the death of a major character. From the speed under burning tankers, to the foot chase the final one was great.

The original was good, the 4th one was great I loved the storyline and the surprises
