I liked it, as long as I stop myself from thinking about it. Once I start thinking about it, the plotholes swallow up the enjoyment.
Like several posters before me, I wish they had ended it with old Clara. It would have been a nice if somewhat bittersweet ending, and we could have started the next season with the Doctor picking up a new companion. Personally, I would have loved it if Ashley became the next companion. I thought she was great in the dream, working well with the doctor and showing a competence and practicality that I would love to see in a companion.
