I'm supposed to go gaga over ''Thief," which arrives with the kind of pedigree that helps TV critics maintain their professional self-esteem. First of all, it's an original drama from FX, the prestige basic-cable home of three TV highs, ''The Shield," ''Rescue Me," and ''Nip/Tuck." Even more than pay channels such as Showtime, FX has forged a distinctive, daring identity, and its shows are year-end Top 10 regulars.
And ''Thief," which premieres tonight at 10, stars Andre Braugher, the implosive/explosive actor who helped fuel the crime-time powerhouse ''Homicide: Life on the Street." With his ''Homicide" cred, along with a pair of fierce eyes on his gravely still face, Braugher has become one of those performers who verge on being over-celebrated for being under-acknowledged. We have to praise him like we should.
