David Tennant was good but the stories seemed to get quite unfathomable when Matt Smith took over, and I haven't watched it since.
I think a lot of this was down to the change of head-writer/executive producer mate.
Russell T Davies was in charge for most of the Ecclestone/Tennant period, and was succeeded by Steven Moffat for the Smith/Capaldi era.
Maybe the unfathomable bent Moffat brought to the series is understandable when one realises he also writes
Sherlock scripts.
I'm reliably informed that Moffat is retiring from Doctor Who at the same time as Capaldi, so there is hop that we might get back to slightly less complicated plotlines.
