I watched the new version and it is totally fine on the interwebs. If the adverts are different on TV (big UK complaint) I it didn't appear any different on the web catch up show. They have done a nice job with the comedic duo, prue leith is just as out of touch and behind the times as mary (maybe a tiny bit less so, but she is much posher so it adds up to the same thing) but what they have done is gathered quite an interesting cast of bakers, which is probably prudent. Filling the dead air when the bakers don't make good telly has been more of a challenge in older episodes IMO. Paul does not have the dominant position as per episode1, smart move,as that would have been a negative.
For me, Prue Leith was someone I aways had heard of, I had never heard of Mary Berry before this show, so MB is no big loss.
