@Reyn,
Last night's CSI was good, despite the fact that they tried to put "Re-Animator" in it's comical gore to shame by having Robert David Hall pull out a brain from an open skull, holding it up in the air and pulling the hemispheres apart with a straight face (I did detect some tongue biting here). I don't think they were going for laughs there, although the whole storyline of the Jesus wanna-bes was one of the most whimsical of the show. I like CSI when they make fun of themselves. I'm starting to like Laurence Fishburne's character -- he had a nice turn at the end of last night's show with the whimsy. You're right, they're going to have to set their sights higher on the imagination gauge, but, of course, they can't go as far out on a limb as "Fringe," which is now beginning to make "The X Files" as tame as a bedtime story.
Since the serial killer of a past running plot was caught, the CIA guy's remark about "we've found another one" when he calls in about the little boy and that last scene means there's a new sub-plot that has to be resolved, but I'm guessing next season.
"Eleventh Hour" is one of the best written new shows as well as "The Mentalist," and I'm beginning to get warmed up to the new "Castle."
It's kind of "Murder She Wrote" updated with a male crime novel author and they aren't taking themselves too seriously.
There always in trouble of getting to formulated but of all of them, I think "Fringe" can keep taking it to a new level.
