I like what I've read so far about Matt Smith. It appears that he was meant for the role, if what Mr. Moffat had to say means anything. Since he is the primary writer for the new series. I like the fact that Matt is young and seems relatively un-marred by stardom. He can grow and mature as The Doctor and make the role into a classic. I think we are in for a great new season.
It will be interesting to see who they choose as his first companion. I do hope it doesn't become a sappy love struck teeny, but then again he is a youngish man. Much more believable were he to have 19 or 20 year old companion who falls in love with him. More so than Rose's infatuation with the Doctor. The age difference though not unheard of was just a bit too close to jail bait for comfort.
We will have to see. I am quite looking forward to the new season.
