I'm a big fan of unfolding the story/ back-story as you go along style of drama but the unraveling is happening so slowly in The Cult that I'm finding it pretty unengaging. So technically the series looks great, the performances with a few exceptions are fine, but the pace of the story telling is killing the story.
There's some good stuff in there but it's so snuggly wrapped up in the 'mystery' that it's hard to watch. Too much set-up people.
Also the music is all wrong- if only they'd gone for something warmer... it would have been a lot more watchable. It's a small thing but I think it makes a huge difference.
