9. Sylar turns good on "Heroes," NBC. Recently, this once promising drama has been going through so many plot twists, double-crosses, flashbacks, flash-forwards, and alternative futures that watching it is like going to the optometrist: Is it better like this [switch!] or this? The worst switcheroo so far was turning Sylar (Zachary Quinto) from a stone-cold psycho serial killer into an approval-starved company man who eagerly went to work alongside his former mortal enemies, falling in love along the way. Seeing Sylar subsequently revert to his villainous ways (this time with post-murder witticisms) was a relief but also suggested that sometimes TV producers just make this stuff up as they go along. (Hi, "Lost"!)
