I try to present a balance here. I wouldn't say I prefer one type of fanfic over the other. My favorite stories have elements of comedy and tragedy in them, in the same way that the series does. Kel's writing is the best example of that, imho.

I understand the impulse to write them as deranged psychopaths. Scully does crazy stuff but only when she's under the influence of the Consortium. But Mulder does stuff that should get him kicked out of the FBI, if not committed to a mental institution, and on a fairly regular basis.
