For the most part I liked it! However there were somethings I didn't like. SPOILERS AHEAD SO READ AT OWN RISK!!!!
I did like how most of the doctors were honored, though I would have liked more of the actors to be brought in or at least offered the chance. I loved David Tennant being back on.
The things I didn't like were Moffat's style. Though to be fair I don't like a lot of his stuff. The opening felt a bit rushed/wibbily wobbily which I can understand because it's Doctor Who, but Davies pulled it off much more coherently than Moffat does imo.
I also didn't get why Billie Piper was in there. She didn't do much and reminded me too much of scrouge and the ghost of christmas past.....
I also would have liked to see how he and Clara got out at the end of the season episode..... maybe I missed something?
And finally while I like the fact that Gallifrey was brought back and that now he's going to go look for it I'm a bit miffed that in 78 minuets Moffat took away the tragedy from the character. Personally it felt like a bit of a cop out to me on how easy it was to do this considering it was supposed to be impossible. I would have liked to see it be a little bit harder to do.
All that being said I liked it and the above's just me nitpicking and giving my opinion. I do like the new doors it's opened though.
