Watching Touching Evil right now (the US series). A law enforcement agent gets shot in the head and loses all sense of inhibition, causing him to become quirky, random and somewhat abrasive in social situations. He befriends and takes advice from a schizophrenic math genius who thinks he's an alien. He goes into a trance when he sees the traffic light turn red. In the episode I'm currently on, he's demanding a suspect to take off his shirt so he can see if he has a tattoo related to a murder case. Of course his partner is an attractive blond woman who initially has some difficulty putting up with his antics, although she's starting to warm up to him.

Now that the obligatory DP connection has been made (the description was part of what made me track it down in the first place), I have to say it's a nice blend of CSI and Law and Order- neither of which I follow- with more thematic depth and emphasis on character development. It's quite well written, I think, not being a huge TV watcher- it only ran for about 13 episodes before it was canceled, but I'm enjoying it so far.

I've also got American Gothic waiting on the backburner for more Satanic small town hijinks, and just finished Wild Palms and Profit. They're all canceled TV series or miniseries, so they don't eat up too much time, and most of them I tracked down because "Twin Peaks" was included in the description of their plots- Basically, they were all too weird for television. If you're in the mood for shows that were short-lived because audiences couldn't handle them for reasons other than mediocrity (the first episode of Profit ends with the protagonist passionately making out with a blond woman, followed by the line "Hi, mom"), these might be worth checking out.

if you like something more "psycho" watch "Session 9" a very underrated movie.
About series that will NEVER hit the television format i highly suggest you Masters of Horror and Fear Itself.
