I caught up with the first 2 episodes, I think I saw somewhere that this is the 2nd series, but If so I completely missed the first.
Those first 2 shows have made it clear that this will be an irritating watch for those of us who have been abroad quite a bit, the woman who got booted off the first episode had been given an extra clue ("Colmar"), but hadn't the wit to use it. What a good idea to go on a geography based game show and not bother to look at some maps first?
In the 2nd show, the contestant who is a nuclear scientist (?? Lord help us all?!) saw a clue that was an anagram of Matterhorn, and helpfully didn't read it properly, repeating the error several times (any of the others could have corrected her, only one at most noticed).
One of the ten contestants left partway through episode one, having apparently not read enough of the notes to work out that they'd be on a coach for a while, not getting the delights of home cooking!
For me the main problem of the show is almost constantly hearing Rob Brydon's super-smug voice-over, or his patronising little speeches to or about the contestants. At least they didn't pick Sara Pascoe, I suppose, now reinstated to try and make Sewing Bee unwatchable again! (record it, then speed through her bits . . .).
