In a mostly-glowing review, the Globe's Liam Lacey calls Ghost Town an "innovative romantic comedy that is a mixture of British spice and American sugar." (Lacey also notes that Gervais is part-Canadian... File that away for future cocktail party trivia!)
Meanwhile, over at the CBC, Martin Morrow calls the flick a "tepid supernatural rom-com" and "a largely uninspired parody of Ghost." He praises Gervais, though, and here's a bang-on excerpt from that bit of the review:
Like some of the great comedians (Peter Sellers springs to mind), Gervais seems to possess an inner core of melancholy. At his best, he walks the knife-edge between laughter and pathos beautifully. Think of that funny/mortifying scene in Extras when David Bowie made up a nasty song mocking Andy Millman — Andy sat there, listening politely, his ego crumbling like a biscuit in hot tea. Ghost Town doesn’t give Gervais the same opportunity for subtlety.
Slate's Dana Stevens agrees that Ghost Town "doesn't do justice to the manifold gifts of Ricky Gervais" - but she's willing to give the film some credit. It does, she writes, have "inspired casting, a few memorable scenes, and enough laughs that mainstream U.S. audiences may finally get the point of that doughy English guy with the pointy canine teeth and the high-pitched giggle."
As for me, I'm still planning to catch this one in theaters. I said above that Martin Morrow's comment was bang on - but that's exactly my problem with Ricky Gervais. That "core of melancholy" throws this cheesy-ending-loving gal right off: too much of 'The Office' and I've been known to sink into a deep funk.
If Ghost Town is vintage Gervais with some syrup mixed in, that sounds just sweet enough for me.
