I might give Torchwood another go soon. It rarely reached its potential but it had its moments. Also works really well as a drinking game. Aerial shot of Cardiff? Character standing on a tall building? They type really quickly to make stuff happen? Camera suddenly zooms in just a tiny bit? Then does it again? Then keeps doing it and you can no longer not see it? The answer is yes and you are now smashed.

MUST give Children of Earth (series 3) a watch. Its brilliant in no small part because of the mighty P-Cap. One of the few times the show really got its "grown up Doctor Who" concept right. Its got proper classic British Sci-Fi (like Quatermass) vibes to it.
