29. Grace and Frankie

To its credit, Grace and Frankie creates a marvelously relaxing ambience, and it's hard to not feel warmth toward Sam Waterston and Martin Sheen as lovers. But it's much better at developing its beach-house atmosphere than it is at emotional nuance or characters who aren't caricatures. The frustrating thing about this series is the gap between its promise and its execution — the complete lack of nuance makes it cornier than an Iowa primary, and in the instances where you want it to slide into full-on Kleenex-tearjerker moments, it punts.
