We haven't watched that yet. The problem is, we don't settle to watch TV until around 9 pm, by which time my brain is tired out and watching a serious drama in Welsh is difficult. We may give Bang! a try, but we need to watch it on an night we settle in front of the TV a bit earlier.
The programmes we like are the shorter, factual ones. Favourites include 3 Lle, 100 Lle and 4 Wal. We like seeing the places we recognise and 3 Lle is particularly interesting because of the associations the person of the week has with each place.
