The whole series is freakin’ hysterical. Check it out if you get a chance.
/end “Extras” hijack
Big Bang Theory - want to see a triangle between Leonard, Penny and the nerdy/smart girl Leslie Winkle.
House: Thirteen must die, quickly and messily. Cameron throwing herself on the funeral pyre would be an added bonus. Cuddy reverts to S1 form and cuts down tremendously on the amount of shit she allows House to get away with. Foreman is given an actual purpose. Chase is allowed to have more than one line per episode. Kumar and Taub, carry on.
Seventh-ing(?) the wish for a Stephen Fry cameo, and Rowan Atkinson wouldn’t go amiss either.
Terminator: Confirmation of a romantic subtext/plot between two of the lead characters. (And, probably, a season renewal notice.)
After that…huh, I don’t think I’m actually following any other shows that aren’t just slapstick, at the moment. Maybe I’m gunshy after watching so many get canceled; turn into convoluted soap operas, and/or overrun by “witty” commentary on current events, or just build up to a horribly sad finale.
There is Mythbusters, though. I’d like to see them do an episode on zombies. Rarrgh!
Oh, let’s add on some Tim McInnerny. Paging Doctor Darling.
**Boston Legal **- Concentrate more on Denny and Alan and less on the rest of the cast. Especially Jerry and the annoying British chick. If fact, get rid of the British chick altogether, I can’t stand her.
Also, drop the preachiness. You can make a political point whithout having to hammer on it.
Just let me enjoy Denny being Denny and let the man SHOOT someone! 
And naked. Strong, sane, and naked.
Big Love: I don’t know how they’d keep her in the plot afterwards, but I’d love to see Barb finally leave Bill’s sorry corrupt ass and get on with her life, while Bill and Roman work together to oust Roman and Bill becomes heir apparent to the compound. (Interesting would be if Bill cemented his heir apparency and officially sold his soul with an engagement to Rhonda.)
As Harry Dean Stanton is 82 and looks a bit the worse for wear (though he’s never looked vibrant and healthy) I hope they’re already filming. He’s great in that role and I can’t think of anybody who’d do a good job of replacing him.
Lost: I want to see how they get back to the island, and I want to learn who survived on the island.
Supernatural: I want more hilarious episodes like “Mystery Spot”(the one that was like Groundhog Day).
Heroes: I just want it to not suck. It that enough?
Pushing Daisies: I just want a whole season and to see it renewed for a third season.
