I'm enjoying it. Pace is fine as I think it's going to be like broadchurch and scandidramas and one case for the series.
Yes reminiscent of life on Mars to some degree but that may just be due to portraying the same era (if you look at period dramas made in 70's/80's/90's portraying the same eras there's similarities eg 50's everyone into rock n roll, 60's always swinging and Beatles music)
LOVING the soundtrack hoping they release it.
