-The reboot of Star Trek probably wouldn't be as dark as OTL (but most likely still action packed, that's the general trend regardless of the economy)
The first of the JJ Abrams reboot Star Trek movies was already produced before the recession really kicked in, so I doubt that would be impacted any. I remember watching the first major preview of it in 2008 when I went to see Quantum of Solace.
Speaking of which, no economc downturn, you would probably see Daniel Craig's third James Bond film, Skyfall, or whatever it would end up being called, being filmed and released in 2010 or 2011, instead of having to wait all the way until 2012.
As far as smaller shows, Stargate SG-1 in the year or so before the recession, released two direct to DVD films that did fairly well for what they amounted to. Before the recession and financial troubles with MGM, there where plans for at least one additional direct to DVD film for SG-1, and at least one film planned for Stargate: Atlantis, both of which where ultimately casualties of the recession.
As far as broader issues. A lot of older folks ended up loosing all or significant portions of their retirement savings and 401K savings when the stock market crashed. This resulted in a lot of people that should have been retiring either not retiring and staying in their jobs longer, or for those that lost jobs, they still actively sought after employment opportunities. This ended up with a fair number of younger people, those that had just turned 18 and graduated high school, or those that where recent college graduates, suddenly having to compete with a lot of older workers that found themselves not financially ready or able to retire. I've seen and felt it myself even to today with a lot of older people leaving the workforce, at a lot of younger people such as myself that graduated around the time of the recession really not being able to get any sort of serious career going.
