I have read some less than stellar reviews of this show but I watched the first three episodes nonetheless. The reviewers are correct in that the show does not pass up very many cop show clichés. LA setting, bad white guy black good guy, bad Russians, bad former military, nasty black woman in charge, smarmy lawyer, killer hot women, cop drives classic Detroit iron and on and on. You get the idea.
All that said, I will always give Jerry Bruckheimer produced shows a shot. He invented a genre with CSI and Top Gun remains little Tom Chruis' best movie. This one is beginning to grow on me.
