Thoughts? A lot of the people I've talked to don't seem to like it, but I thought it was a fitting swan song for Matt Smith/Eleven. It reminded me a little more of the older regeneration stories like Caves of the Androzani and Logopolis, mostly low key with explosive finishes. As much as I like Tennant/Ten, his regeneration story was so overblown in presentation, it put me off a little.
In general, it seems to me that a lot of the people I've talked to that have only really watched newer Who didn't like it. and I'm not sure they'll like where the show is going, as Moffat seems to want to steer it into a slower paced but more layered direction. Older Who fans like myself all seemed to like it too, which is a good indication of my previous theory. and Capaldi looks promising!
