Spencer and Christian are trying to answer one question: what is the best Vin Diesel movie? There's only one way to find out, and that's by going through every single one and putting them through a rigorous scientific method known as The Diesel System. This scientific method just happens to sound like people goofing around and making jokes about Vin Diesel movies, but we assure you that we take it very seriously.

Rotten Tomatoes seems to think that Vin Diesel's action/fantasy romp in The Last Witch Hunter is one of his worst movies, but what does The Diesel System think of Caulder, the immortal hero based on Vin's real life Dungeons & Dragons character? The only way to know is to put it to the test.

And also it's funny. This is one of those funny podcasts about movies.
