Studio execs and producers always have been, and always will be, effing stupid. Look at the CW, a network that won't push great shows such as Supernatural and Reaper, instead concentrating on turds such as Gossip Girl.As much as I'd love to think this is pure rumor, I don't think the show has much of a chance at coming back. I already contributed to a letter writing campaign. Sad. They were finally getting it right and *poof*.
There is a film project being done by Larson, but that's been in development hell for years. Then again, they finally made "Watchmen" so who knows?
As for any future TV projects, I'd say what this show did was to give them a good template of what not to do in many respects. Hopefully any future TV projects will avoid the pitfalls that this show went crashing into.
CW is chasing the young female audience, so that decision makes good business sense. The only show on that network I watch is Reaper, so it's not good from my perspective, but I can see why they do it.
Knight Rider fell afoul of two trends in the TV biz: mindless braincandy for the masses is now getting really mindless, and even a show about a talking car is apparently too complicated and off-putting for that market. OTOH, the niche audience for sf/f is getting fussier, and Knight Rider just isn't smart enough to cater to them. It needed to be a lot smarter or a lot, lot dumber.
Plus, Knight Rider was being heavily supported by auto industry product placement, and I doubt anyone has money in the budget for those kinds of frills anymore.
