“Ghost Town,” 19 October 2009, DVD. Ricky Gervais is mildly amusing as Bertram Pincus, an antisocial dentist who dies during a colonoscopy and is revived only to find he can see the dead who died with things unresolved and they can see him. One, a sleazy stock guy played by Greg Kinnear, wants him to deal with his ex-wife’s (Tea Leoni, the best thing in the movie), involvement with a new guy. Gervais becomes involved and grows, shock of shocks, a better person for it. A sloppy film with some nice bits but not worth the time
