The quality of the talent is good, I also like the visuals, set up, and of course the girls are very nice and give great performances at the start of the shows. I just have a few critques:
1. When Little Mix provide feedback to the guests, their feedback is always very generic, bland and nice. They never say anything groundbreaking / worth watching (so I always skip it on catch-up).
2. The categories need some work. It's hard to keep track of all the different categories, and some of them feel the same. For example, I would suggest merging 'girl dance group' & 'girl group' into 1 category, keeping the latter. Same for the mixed 'rap R&B group' and 'mixed group'. Then within each of these categories, they can create multiple bands of different styles / genres.
3. The winners may not be the most talented, due to the nature of the audience. This is a highly subjective opinion, but I think the most recent winners of this show, only won because the majority of little mix fans (who consequently watch this show) are young girls, who naturally like boy bands. I don't think they won because of talent. And I could potentially see that concept having a negative impact on the show long term.
However, I will give the show another go, it was entertaining, just requires more tweaks which is kinda normal for the first time round on a show. I'm not sure about it's longevity though, given the nature of some of the points I've outlined above.
