ABC did well with Dancing with the Stars (3.9), and Castle (2.5) which was was up .1 from last week. Castle has been fluctuating around this level so at least it won't drop significantly from here.
CBS did about as well as Fox with How I Met Your Mother (3.4), Accidentally on Purpose (2.8), Two and a Half Men (4.7), The Big Bang Theory (5.0), and CSI: Miami. After the crossover last week, CSI: Miami fell past the ratings for 2 weeks ago. I still can't understand how Two and a Half Men does so much better than How I Met Your Mother. There's also lots of hot women on HIMYM, and the writing is so much better.
Fox did great again with the combo of House (5.0) and Lie to Me (2.7). I've been hearing a lot of good things about Lie to Me this season, especially with the addition of Shawn Ryan as showrunner, and I heard lots of positive comments about the last episode. The ratings are still way down from House, but still decent which is why Fox probably doesn't want to mess with it.
NBC again sucked with Heroes (2.2) and Trauma (1.8). Heroes fell to another low which isn't surprising. From the first 4 volumes, the writing has gotten progressively worse as the parts continue.
