I liked it. I particularly liked the part where Moffat wasn't there anymore, and an actual functional adult who actually made an effort did this one.
...I should stop only posting in DW threads to whine about Moffat.
I hope the villain comes back. There's such an obvious setup for it - the guy is a laughing stock among his people now, so he grows a specific vendetta at the Doctor & friends. Maybe he tracks them down and then just randomly pops up again during an unrelated adventure, could be great. And Jodie seems good at this point, but it's way too early to make any kind of a judgement. It was a post regeneration episode, and she doesn't (...wrote "he doesn't" automatically first before going back to correct myself) even have her Tardis yet. Needs some time.
But it was pretty interesting how my wife was on board, like, immediately. She specifically loved Smith, and was generally fine with the rest of it, but never particularly cared for the show before or after Smith. Then Jodie landed on that train, said her few first lines, and my wife immediately proclaimed her to be her second favorite.
