As per Matthew Weiner's instructions regarding a potential review of Sunday night's two-hour Season 5 premiere of "Mad Men" on AMC, there's not an awful lot I'm allowed to tell you.

Things I specifically can't tell you:

- I can't tell you what year Season 5 is set in, though it has already been spoiled by many outlets that "Mad Men" creator Weiner removed a Dusty Springfield song called "The Look of Love" from the episode because it was pointed out by some critics that the song was not released during the timeframe of the episode. So if you Sherlocks want to know the year badly enough, Google away. (Season 4 took place in 1965.)

Body of Proof (10pm, ABC) - Christina Hendricks (left) of 'Mad Men' plays identical twins in tonight's episode. You can write your own punchline to that if you like. Hendricks plays the identical twin of a beautiful corpse who piques the interest of Ethan (Geoffrey Arend, also left and Hendricks' husband in real life. I'm serious.).

Parenthood (10pm, NBC) - In the finale to what has been a very strong second season, Sarah worries about Amber following an accident, and Kristina offers guidance to Haddie.

Dresscue Me (10:30pm, Planet Green) - The premiere of new reality series following designer and retailer Shareen Mitchell, who specializes in revitalizing vintage clothing (making people wear hand-me-downs). Tonight, she helps spruce up an army wife who hasn't seen her husband in months. Here's our review.

"Tomorrowland" is the title of the "Mad Men" season finale, and the episode looks forward. Season 4, Episode 13 left us feeling optimistic, the way people who visited Disneyland's look into the future must have felt -- until the second half of the 1960s rocketed us into a future that wasn't as bright as we thought it would be. It was a most satisfying ending to thise great season because it makes us eager to see what happens next but filled with dread, too.

Don Draper makes one of his signature impulsive moves, trying to improve himself. Peggy Olson gets high on work. Betty Francis acts like a child. And Joan Harris takes care of herself.

"It's the end of the world." The word gets out that Sterling Cooper Draper Pryce has lost Lucky Strike, and everyone at the agency is shaken in Season 4, Episode 11. Don vows that things will be OK, but nobody is sure that the agency will survive.

And anyone who has been through the economic downturn of the past couple of years knows what the SCDP people are feeling when they watch as their company's fortunes take a horrible turn for the worse and they don't know whether they'll be out of a job soon. It's frightening, but oddly exhilarating, too, as Stan the pig says, "It's the last days of Rome. ... The energy is very good."
