These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Gavin and Stacey
Jerk with a Heart of Gold: Nessa, though at times it's hard to see when the gold shines through. Especially with how she treats Gwen.
Moral Event Horizon: Stacey trying to get pregnant without Gavin knowing. She stops taking her birth control for over a year, and doesn't think to ask him whether he's ready to be a father.
Wangst: Stacey's endless longing for home in series two.
Stacey's prone to this, her wangsting over not being able to have a baby right there and then.
