The DX12 is leaps and bounds in quality over the DX2. DX2 was impressive for it's time. Unfortunately, I have a couple of figures that have disappointed due to qc issues and others that just were outright disappointing. Here's a couple:
-DX1 Joker: roughly a year after I got him, I was changing the pers to match a new pose on my shelf. Wth! The eyes stopped moving. Opened up the head to see shards of plastic. Strange coincidence that the DX Joker 2.0 came up for PO a week after pers broke.
-TF Batsuit Begins Batman/Bruce Wayne: hyped to be ridiculously limited with the crazy flippers in HK hiring maids & whatnot buying multiples. PO open for months afterword. Cool figure but the ankle joint in the boot breaks up into shards.Can't stand on it's own anymore.
-DX Indy: Proto looked pretty good with many hoping for a resculpt before release. Many hoped it would be definitive. Released with weird sunken in eyes and eyeliner. The likeness is so close and really off at the same time.
-Berserker Predator: The body felt like a NECA figure. The sculpting and detail was amazing but that Predator body just seemed a bit too similar to what NECA does with Predator. I don't mean to put NECA down. They make great stuff, but I want my $200 purchase leagues in quality above what you can get for $20.
I am more often wowed by their offerings than not. Their likenesses have raised the bar for the whole industry. With the right lighting and a good photographer, these figures can stand in for movie stills. I even have figures for movies that I downright loathe just because they're so damn impressive! (Specifically, DX Jack Sparrow & Nic Cage Ghost Rider) I only really get disappointed when there's a qc issue that tarnishes my appreciation of the figure or some releases that seem like they're phoning it in. Btw, sorry for the long post.
