I think they need to reformat the last episode, badly - or just remake the entire concept of the show as basically a 'survive 12 weeks and I'll give you some cash for your business'.
It's just become so silly - the idea of coming up with a new logo and video ad and then a light grilling from some experts. They're always bad logos/names, bad videos, and the experts rarely have any question that is really pointed. All the candidates ever say is 'I'm doing XXXX moderately well, I want to make 10 other people do it in 10 new locations and make lots of money'. Great. Airco or pizza, nobody cares at this point. We never hear from them again anyway.
I think it either needs to lean way more into the dragons den style (a bit like the interviews in the previous episode), or simply rebrand the entire show as basically a weekly elimination, scrap even hearing about their business in any detail, and the people with the best business acumen get a cash prize.
