The show was already on Season 6 (!) when I found it and I have watched most of the episodes, season by season, on YouTube. I have found that you can watch some of the seasons on PBS, so check your local listings.
What I love about it is that there seems to be enough time for them to complete each task, so they aren't cutting corners. You get to see the real process they use with parchment paper, different kinds of pans etc. I just love it. The contestants are kind and help each other, give supportive glances if someone gets a harsh critique and are always there to consult on the proper oven temperature.
There are two hosts, Mel and Sue, who add lighthearted commentary and always seem to know the right thing to say if a cake is listing to the left. The hosts take turns announcing the "Star Baker" of the week and who has unfortunately been eliminated.
The judges are cookbook author, Mary Berry and renowned baker, Paul Hollywood - both famous on that side of the pond and its fun to see the bakers nervous to have the duo taste their creations.
Have I convinced you? This is sugar-driven television (for a girl like me) at its best.
