I absolutely loved it! Saw it in the theatre last night which was so much fun.
I knew Peter Capaldi would be great. He's an amazing actor, and the fact that he's a Who fanboy is just icing on the cake. Eleven was my doctor, but I also loved Nine & Ten. Within the first 10 minutes, Twelve had captured my heart as well.
I think part of the reason they hit us over the head with the age was for the kids. The kids I know who have become Who fans recently talked a lot about not wanting a new Doctor. Twelve is so different than Eleven that I think this had to be addressed in some way. I will admit that as an adult, I got a bit sick of it.
I'm glad we got some hot lizard on girl kissing. Strax is stupidly fun, and by the sounds in the audience, kids love him.
I will have to say that the best part of the night was when the show started and we had no sound. A guy in front of us yelled "I've got it!" and soniced the screen. Many cheers were heard when the sound suddenly started working.
