Well I was never a big L&O fan before, but I gotta say I was REALLY digging Goldblum's run on the show this season. He was quirky and fun and just fascinating as hell to watch. It's a shame his partner isn't coming back, because I thought they were great together. But as long as HE's gonna be there, I'll still be watching.
As for D'Onofrio, I thought he was kinda interesting early on, but by the end, it appeared he was just sleep walking through the role. He was kind of like CSI's Grissom... if you sucked out all the personality and warmth. lol
