I have been a viewer of UKTV Food for many years and watched GFL from the beginning. I have to admit that there were the odd times when I would go off it and not watch for a while, but on the whole I found it informative and interesting to watch. It would hold my attention for the hour it was on and I enjoyed the relaxed and informal atmosphere. Whilst I felt Jenni could sometimes be a little overbearing, on the whole she was an excellent presenter, someone who asked the questions of chefs that I would like to ask. I enjoyed watching her interview guests as she seemed genuinely interested in all that they had to say and her interraction with the chefs was excellent. To say she became bigger than the show is a little harsh, to me she made it an entertaining as well as informative programme and there is absolutely nothing wrong with that.
Having tried (and failed) to watch MK several times, I think the difference between the two programmes was the fact that GFL had a presenter and a format that encouraged people to watch, whether you enjoyed cooking or not, where MK would perhaps only appeal to dedicated cooks. And if a programme like GFL would encourage those of the viewing public who might not enjoy cooking to get in the kitchen and cook, then that's no bad thing.
For me, and I presume many other viewers, it's not simply Jenni Barnett that is missed, it's the whole package that was GFL.
