Doctor Who? Oh yes, I know him.

I have seen the blue phone box, and it is good. Yes, “Doctor Who” has won me over. After years of people nudging me to give the show a chance and me, well, not, I finally gave it a try following David Tennant’s Nerd Man win last month. Lo and behold, the Converse-wearing Time Lord has reeled me in, and I feel ready to stamp the word “fan” on my delicate, dorky forehead.

I had shied away from Doctor Who for so long because A) the show’s been on for approximately 117 years and I felt like it was too much to catch up on; B) I had the 1970s-era “Doctor Who” with its gaudy, brightly lit sets and football-scarf wearing Doctor etched in my mind and thought it looked cheesy and C) I wasn’t sure if I could welcome another show into my already crowded, TV-addled brain. I’m happy to report I have leaped over all those hurdles. The reason? Well, let me just warn you. It’s a shallow one:

David Tennant is pretty adorable.

I know. I’m not only stating the obvious, I’m drawing pictures of it and calling it Susie. (I’ve no idea what that means.) Everybody and their mother seems to know about this Tennant thing, and I’m very likely the last one to jump on a very huge bandwagon. I feel I should get credit though for realizing the error of my ways and publicly acknowledging my pop culture crime. Even if I’m tardy,* I still made it to the party. (A rhyme!)

Beyond the aesthetics, I’ve enjoyed the vibe of the show. I know nothing of the backstory, but the show is written well enough for me to dip my toes in without feeling overwhelmed. All I really need to know is that the hot Scottish dude in the long coat travels through time bringing chickies with him and solving problems. Easy enough. I like, too, that the show has a very good dose of humor. Tennant does a nice job of being arrogant, wry and whiny all at the same time without ever losing his charm. And I like that there’s still just the right whiff of subtle cheesiness about the whole thing, what with the slightly rubbery aliens. And although I don’t know the characters well enough to be too invested yet, I get the sense that there’s a strong emotional depth at play. It’s a complete package and it reminds me in a way of “The Avengers,” a show that could be goofy, ridiculous, action-packed and enormously touching in unexpected and welcomed ways.

Now that The Sci-Fi Channel has paired “Battlestar Galactica” and “Doctor Who” together on Friday nights,** I’m in it for the long haul and am looking forward to getting to know the good doctor even more. Even if I am 116 years behind schedule....

* Speaking of “tardy,” the word “Tardis” still makes me think of tartar sauce. Will that ever go away?

** Yes, I stay in and watch sci-fi on Friday nights. I would say it’s a result of getting older but let’s face it, I stayed in and watched sci-fi when I was in college and supposed to be cool, too. Did I mention I’m a big nerd?
