This remains a family favorite. It’s almost magical how well and persistently everything works — right down to Dennis Boutsikaris’ amiable psychiatrist and Lorraine Bracco (New York as all get-out) as Billy Caufield's ex-girlfriend.
Oddly enough, it wasn’t that well-regarded on its release, but I’ve always found the film charming, Coming off Beetlejuice, Keaton is the ostensible star, and his character’s tethered violence gives the story a mild edge (which it badly needs). He gets the cruder gags and he's just as effective as you would expect.
And yet the real treasure here is Christopher Lloyd, who gives a complex, layered performance that is sometimes sad, sometimes carefully annoying but more often very, very funny.
To be sure, there are cliched elements and it’s going to feel a touch dated in spots — especially toward the end.
But forgive its age. Just give yourself to it for an hour and a half and I think you’ll have a wonderful time.
