After four episodes, I think I can say that I'll enjoy Capaldi as the Doctor way more than I enjoyed Smith. I had hard time liking him as the Doctor, especially after Tennant's portrayal. Looking back though, I must say that Tennant wasn't has good as I remembered him, probably because I've watched a couple of Hartner and Baker's episodes. Ecclestone was indeed a great follow-up of the War Doctor. Now back to Cappaldi. He seems to bring a "vintage" look to the doctor, if I can say. He has a very dark eccentric side and seems to look like he has less humans emotions or connection with them, wich I think is better has he's less likely to have another useless romantic story with one of his companions.
