ObiWan, just to warn you.
The first season of TW is a bit on the ordinary side. Very monster of the week and trying to be sexy.
The second season was an improvement, and has a startling finale, but still just okay.
TW s3, Children of Earth... is utterly amazing. Only five eps, but after each you sit there feeling as iff you been blasted by some really intense radiation, or the strongest storm you've ever faced. it's worth watching 1 & 2 to get to 3.
