Yes, this is "Raising Hope" for the carpaccio crowd, but like that gone-but-not-forgetten Fox sitcom set in the no-frills aisle, the potential for schmaltziness is more than balanced by the show's oddball sensibilities.
Brewster classes up the proceedings considerably with comic timing the rest of the cast ought to study.... Grandfathered doesn’t have too many solid punchlines--it gets by on charm, which Stamos possesses in abundance.
After one episode of Grandfathered, it’s easy to feel like you’ve seen the first three seasons, especially if Jimmy is going to constantly be presented choices between bedding desirable women and looking after the moppet who has fallen into his lap.
Grandfathered is half-assed even by the exposition-dump standards of network pilots for I AM programs. Little of its dialogue even sounds like dialogue; most of it, in fact, sounds like stuff writers might scribble in their notebooks on a page marked, "IDEAS FOR DIALOGUE: MUST WRITE BEFORE FRIDAY!!!"
