The BBC started to move the programme around the schedules. (One episode was directly after the repeat of the previous one.) But at least the BBC has allowed me to stop watching without having to make a conscious decision.
With regard to the last episode I did watch, I had to start recording it after five minutes, in the hope that the ability to fast forward would make it more watchable; it didn't.
Apart from the action-lite approach, what I found most irritating with the episodes I saw were the flashbacks. The flashbacks on, for example, Lost (for the couple of seasons I watched that) were fine, possibly because they had one character from the "present". Defying Gravity has the same cast list for the "present" and the flashbacks; instead of gaining insights into the behaviour and attitude of each character (as in Lost), the technque came across to me as a cheap way of building whole episodes out of not very much when used in Defying Gravity.
