Like pretty much all of them really, although I have a tendency to find Rob Brydon a bit annoying so never warmed to Bryn that much. Lovely character though, just not my favourite.
I know Gavin and Stacey themselves are routinely pissed on by fans for being too boring or whatever but they're meant to be the sort-of "straight men" surrounded by the eccentric family and it's fair enough really. Gavin is obviously that tried and tested "Martin Freeman from the Office" character (touched upon on an episode of Never Mind the Buzzcocks, IIRC
) and Stacey is just... the sweet one? Although it took me a while to not hate her voice
I liked Dave Coaches too, forgot to mention him.
But the reunion will be sad without Doris
absolute goldmine of one-liners and comedy moments.
