I really enjoyed Law & Order: Criminal Intent. Robert Goren is very similar to Reid; both of them have schizophrenic mothers they are responsible for, fathers that abandoned them, and they are very
cerebral. Goren solves the cases using profiling as well as other detective methods. One difference is Goren's character is a bit more socially aware and is much more comfortable around the ladies. I've seen a few fanfics that feature Goren and Reid, maybe one or two. Toward the end of the series, the writing nosedived and they heaped too much angst on Goren's character but overall I was sad to see it canceled.
