Why Smith was canceled
If the comments section here is any indication, even though Smith was canceled rather quickly by CBS, it actually had a lot of fans. Of course, we didn't get 10 million comments, so "a lot" wasn't really enough.
TV Guide has a breakdown on why the show was canceled. It seemed like it could be a hit: West Wing/ER producer John Wells, big stars like Ray Liotta and Virginia Madsen, and lots of hype by CBS, but what happened? People have speculated that it was because the gang of crooks on the show weren't likable, but the magazine says that it was more the price of the show. Each episode cost about $3 million dollars!
I wonder how much that awful motorcycle chase with Simon Baker cost to film?
