Now that they are nearing the end of their contract and have been on a hiatus for 2 years I feel like we can kinda openly talk about why this group just didn't work. Of course people can endlessly blame company and other outside factor but when you look at the facts on hand you have group with one of the best discographies and I am a firm believer that good songs need just a little push to become hits and WeMe just didn't have that little push in them.
Here are the 3 highlights of what exactly was wrong with WekiMeki.
1) Visuals.
First of all, lets not beat around the bush, the group is severely lacking in visuals. Yes, I know most of you aren't comfortable talking about this specific aspect cause you think it makes you a horrible person compared to when you bash artists for charting, but it is one of the key elements of Kpop, deal with it. Debuting a group with such lacking visuals was a pretty bad idea. Especially during the 3rd gen, when we started getting groups with no visual holes like Twice and Red Velvet and a lot of fans, kfans more so, started getting very demanding about it, which started whole another drama with trolls purposely voting for non visual trainees during Produce48 to "ruin" the group.
2) Talent.
Okay, but idols who lack visuals can always make up for it with the talent, right? Absolutely, and we've seen that happening many times. But the thing is Weki Meki members don't have the talent to make up for their lack of visuals. Of course they can hold a tune, but they don't have the skills and charisma of Mamamoo for example. So you have a group with sub part visuals + sub part talent.
3) Doyeon.
I just said WekiMeki lacked visuals and you've probably prepared your Doyeon gifs and pics to prove me wrong but that is the thing, Doyeon makes things worse. She's just too perfect, she shines too bright. Without her they'd at least look average, but when with Doyeon around, the rest look like back up dancers. And they were perfectly aware of this it seems, because they'd always hide Doyeon in the group pics, like look at this pic it is so funny. Or look at their usual standing formation.
Conclusion, it is not that Fantagio doesn't know how to promote groups, it is more so that they don't know how to make them. It as obvious they'd flop after this comment section.
