If you used to watch Countdown With Keith Olbermann when it was on MSNBC, then you have a pretty good idea what it’s like on Current based on the first show tonight. The theme music from Beethoven’s 9th Symphony, the “Worst Persons In The World” segment, story, and guest selection, throwing his script at the camera, righteous indignation — all virtually identical. But there are two differences: Olbermann says his show will run 63 minutes a night, which means it will cut into the opening of Rachel Maddow on MSNBC. Also, Olbermann’s attacks on big business sound like he’s more interested in wooing viewers from public access television than from MSNBC. Tonight’s segments included filmmaker Michael Moore blasting the war in Libya, former Nixon lawyer John Dean attacking Supreme Court Justice Clarence Thomas’ alleged conflicts of interest, and Daily Kos’ Markos Moulitsas discussing the GOP presidential candidates and his run-ins with MSNBC. We’ll see how well it wears.
