Watch It! For April 29, 2008

David Cook 

As usual, Tuesday night is rollover night, in which most of the networks don’t bother to schedule anything up against das juggernaut. There’s always the latest installment of “Carrier” (8 p.m., PBS), or there’s “Reaper” (8 p.m., CW), in which Michael Ian Black reverts to demon form (I mean, of course, his character, Tony), but even that geek-cult show is on immediately following the televisual death machine that is “American Idol” (7 p.m., Fox).

Tulsa’s David Cook is currently ranked at No. 1 on Entertainment Weekly’s “American Idol” Power List, having performed most consistently and surprised many fans with his Mariah Carey and Andrew Lloyd Webber Week performances. Now, it’s Neil Diamond Week, which I imagine could be difficult, given how idiosyncratic Diamond’s songs are — they are hard to cover, to say the least, without resorting to Neil-like growling and hysterics. See Cook defend the No. 1 spot tonight.
