Where'd you hear that? So far as I know, Las Vegas has gotten a full 22-episode order for its second year and is doing reasonably well, with ratings expected to pick up after Monday Night Football ends.
Of course, the crossover will look a little goofy with Crossing Jordan 16:9 and Vegas 4:3.
If I'd never seen an episode of Las Vegas, and only went by this episode of Crossing Jordan, I don't think I'd like Las Vegas's cast that much. Ed comes across way too strong, and Danny just seems indignant the whole time, and Sam is just looking for her next whale.
The Las Vegas portion was funny as hell in the first half hour with Woody getting Vegas fever, and Jordan going undercover. Ed's uncomfortableness being around Gillian 24/7 is always fun to watch. Having Snoop Dogg walk in on Ed and Gillian was classic. The wrap-up to the actual crime case was okay, nothing awe-inspiring, but finally Woody gets paid off in spades at the end, though he has to give up his Viper, and the Mortician from Boston has made a friend in Vegas. Danny and the one with the big chest (Jordan's description) finally go out on their date (cheap and with an ice cream theme on rooftop of the casino).
I've only seen one episode of Vegas before, and I watched Crossing Jordan infrequently. That said, I found the Crossing Jordan half of this two-parter much more interesting. The Vegas portion felt more scattered with its four-odd disconnected stories.
The one other Vegas episode I've seen -- Danny returns from service and struggles through Post-Tramautic Stress Disorder -- was much better.
I think cross-overs are just hard to do. It seems difficult for writers to integrate two different styles and while keeping each show true itself.
