It's tempting to say that the problem with The Ghost Comes Home is its cast, as anyone who approaches a film in which Frank Morgan, the title character of The Wizard of Oz, is married to Billie Burke, the Glinda of Oz, is going to expect much more than this meek little comedy delivers. But that would be wrong to say, because whatever expectations Morgan and Burke cause us to bring with us, they are the only thing that makes Ghost worth watching. Oh, it's not a terrible film and it's not painful to watch; it's just unfortunately tame and rather farfetched. Part of the problem is its premise, but the truth is that had it a better screenplay, with juicier characters and livelier, more surprising dialogue, we wouldn't really care about the premise. It's also possible that a truly imaginative director might have been able to transform Ghost into a more amusing, faster-paced entertainment. The supporting cast is fine, but it's Burke and especially Morgan that carry the film. Morgan is charming, sweet and lovable -- and thank goodness he's around to keep Ghost alive.
