I jumped off the bandwagon too, like Angelo. Years ago.
I wouldn't suggest to sell the majority of your collection as you may regret it, but maybe figures you don't care about. There are some great figures to keep imo.
I had pretty much everything at some point, including the Toy Fair exclusives (the hardest to get), I was completely hypnotized by this line of figures (like when you get deep into any kind of collection of some specific stuff), but several things made me realize I had to stop (I sold most of my collection):
1) There was an objective drop of quality (of selected materials & headsculpts & attention to detail) happening around 2018 if I recall. Maybe it was 2017. I'll say this: too much vinyl. I never understood this.
2) They were beginning their tendency to modify the actual look of the characters and add their touch. Now I wouldn't have a problem with that had this line begun like this (and I wouldn't have invested so much in it). But they begun with The Dark Knight Returns figure, and it was dead on. It was the comic book character, not a fancy re-interpretation. And most of the early line was very faithful to the characters (Captain Kirk, Spock, Flash, the BvS line, the comic book Spider-Man...). Sometimes there were some changes, but it was still acceptable. Then it became THEIR thing, their characters, and the line had no more coherence at all. When they began their thing with the "ascending knight" batman, it's when I realized it was not what I wanted. Especially when we already had a bunch of great (and better & more faithful) Batman figures.
3) Way too many variants of the same figure, and this was happening for almost every figure. I'm not even talking about disguised re-issues (like Spec Ops Punisher). I was buying characters I had no care about just because I loved this line and wanted to support it, but it was also getting to the point I HAD to get every variant. Then I looked at my shelf and was thinking "what am I doing?". When you have 3 Deadpool, 3 Wolverine, 3 Spider-man, 3 (or maybe even 4) Punisher and so on, it's getting ridiculous. Especially with the Toy Fair variants which were terribly expensive because they're so limited and only given to a selected few.
4) Not enough villains, and the problem is the villains they released are mostly their interpretation of the villains. I wanted a Dark Knight Returns Joker. I did get Darkseid, and kept it, because this character has been let down by most companies, but it's still not the Darkseid I hoped for. Again, too much vinyl.
Now I understand they have to make profits, and they have to rely on variants to sell a lot of the same figure and keep people in the loop. Quality material & tailoring gets more & more expensive hence why they rely on vinyl & cheap tailoring more than they used to.
It's also cheaper for them to make their own characters, that way they just pay for the global licence, but they don't have to pay for a specific character.
I get this. But the thing is, I didn't view this line like this. When it began, it looked like a passion project, that could eventually fail.
I remember the first time I saw those Mezco figures in person, with the first figures from the line (The Dark Knight Returns, Spock, Frankenstein & others) and I thought "wow this is so perfect, this is so cute". The tailoring (the lines... it was perfect!), the headsculpts & attention to detail were perfection. And this format was the icing on the cake, they looked like mini Hot Toys. I figured whoever was behind this had great tastes.
Now there are loads of figures & variants, the quality has dropped so much, most of the characters don't remind me of anything, especially with anything Batman-related.
But that's not to say everything is garbage in this line. Once in a while, they do some very cool stuff. Their Reeve Superman looks very cool (haven't bought it as I don't collect this line anymore), their upcoming Predator looks perfect, their Popeye line is great. But how many poor figures have they released in between? Way too much. I saw the new line of figures recently in the same shop I discovered the line originally, years ago, and while they don't look TOO bad, it's a far cry from what this line used to be. It's like it's handled by completely different persons who have poor tastes!
I just wish they had released way less figures, maintained top quality tailoring, adapt the characters very faithfully, and pick the right characters.
At this point, even if they do release one or two cool figures now & then, I don't want to buy them, they ruined the line for me. It's weird, because I could be even more harsh with Hot Toys, but I've never wanted to own every Hot Toys figure. I never saw Hot Toys doing a line of figures. I see each figure separately. But this One:12 line, I saw it as a true collection of a lifetime. What a missed opportunity (all of this is just my opinion of course).
