I'm mixed about THB. We've watched several of their shows, but I think our favorite is a non-cooking one, "Pubs That Built Britain."
Dave, I like. He seems genuine, and he's goofy, but it a very mild, low-key way. Si...sigh...there's too much mugging and face-pulling going on. He's like a hyperactive kid vying for constant attention. His schtick gets tiresome after a (very short) while. I also get the feeling that Dave is the real cook in that partnership, and Si is there to mix things and say "dude" at the end of every sentence.
It's always like that with teams - you like one and dislike the other. I had the same reaction to Two Fat Ladies when they were on.
So we've seen the pubs show, and their series about chicken (that was excellent), and maybe one or two specials, like a Christmas special or something, and now we're watching one where they show how to do posh food on the cheap, and they reward a deserving person/family at the end with their cheap/posh meal.
I could do without the last bit, because if I'm watching a cooking show, I don't really need a subplot playing at my emotions, but it's a nice diversion. We watch them over weekend breakfasts.
