I recommend visiting combom.co.uk for interesting Who updates and whatnot...

There wasn't too much story to it and the audience was left to guess on much, even where it was mostly explained. Whatever story there was didn't ultimately matter, at all. The Doctor's regeneration was anticlimactic, immediately preceded by major fan service. Too much deus ex machina, even for Who. Capaldi's first words were lame. There were things to like, brought in from previous episodes, but it was in vain.
