Repo Man (1984)

 

The Oxford Murders (2008)

At Oxford University, a professor and a grad student work together to try to stop a potential series of murders seemingly linked by mathematical symbols.

Good to look at, great actors and lovely locations don't help much with a convoluted plot with an impossibly contrived ending, and the pseudo-science (especially math and philosophy) utilized solving the mystery is an aggravating insult for anyone who uses a brain.
