Capaldi Christmas List: What I hope to see from the Twelfth Doctor

A "Doctor Who" regeneration is the only time you can go from being dejectedly sad to ridiculously happy in less than 30 seconds.

After the gleaming yellow dust explodes from Matt Smith's head and hands, we will finally get to see Peter Capaldi as the old time traveler. There's no telling what kind of Doctor he will be, whether he will be the potty-mouthed Doctor inspired by one of Capaldi's previous roles or the redemptive Doctor who has found closure after the 50th anniversary. Jenna Coleman (that is, your Impossible Girl, Clara Oswald) said the show will have a different feel when Capaldi begins his run. Speculations abound, so here is one more for your trouble.

These are the traits I hope to see from the Twelfth Doctor:
1. A polar opposite of Matt Smith. If Eleven was playful and childlike, Twelve must be sophisticated and mature. Twelve is an older doctor, so I expect a greater level of maturity.
2. Sarcastically funny. Eleven's style of funny was a silly-funny. I don't expect Twelve to jump in front of his enemies yelling "Look at me! I'm a target!" He better not twirl and spin around his TARDIS console. Twelve should go for witty, sarcastic humor--similar to Nine and Ten, with a little more edge.
3. Edgier, but not darker. Eleven was becoming "Dark Eleven" following the death of the Ponds. Come on, guys. The "dark and conflicted" persona has been far overdone. I doubt Capaldi will take that route following the result of the 50th anniversary. I do hope, however, Capaldi will bring a sharper edge to the role. He must be unconventional, in-your-face and passionate, without the proverbial angst.
5. Romantic and charming (just for you, Sweetie!). River Song needs to come back for Twelve. Now that the Doctor is older, River Song has a more suitable partner. Imagine the chemistry between the two. They need to experience the "dating" stage River Song used to describe in Seasons 5-7.

Obviously, Capaldi might not satisfy all of those when his time comes. What I want to see is a tougher, edgier, wiser character--someone who is a drastically far cry from Eleven. But that's just me. Hope those are some good ideas for you, Moffat.

Here is the extended trailer for "The Time of the Doctor," airing Christmas Day (that's on Wednesday, guys!).
