I'm currently trying to watch all these US shows simultaneously:

HEROES - enough said
DEXTER - darkly comic cop show, now in 2nd series
REAPER - Kevin Smith esque teen comedic horror show, like Buffy
BIONIC WOMAN - Give it a go - Michelle Ryan is on top form.
THE BIG BANG THEORY - Nerds sharing a flat
and starting Jan 1st:
TERMINATOR: THE SARAH CONNOR CHRONICLES
- Already seen the pilot - looks really good. Follows on from T2

Niiice, i remember hearing about Terminator series, shall look out for it. Im watching Heroes aswell, its probely the best show on t.v at the moment apart from the Peter S show that is
