Micacle Day's problem was that it was set in America. The charm of Torchwood was seeing all those high-concept TV tropes playing out in Cardiff. Transplant that to America and it just gets lost in shuffle.
Nah, it could've been fine set in America if Starz hadn't demanded double the episodes and Rex had been played more enjoyable (And upping the sex didn't help, the first scene was completely gratuitous, the second scene had a purpose so would've been fine in isolation)

Where are we going? And why are we in this Handbasket?
