While these minis are new, they are pretty standard, traditional minis from the 90's era, regarding poses. Okay for beginners, but great for experienced miniature gamers/painters and/or modelers.
The problem with KoW minis is not in the sculpts, it is their execution in the molding process. Mold lines make their typical appearance, as can be expected, but many minis and some sculpts in particular suffer from excessive flashing at the mold joins. A clear sign of low-quality molds, a lack of pressure during the molding process when the plastic &/or resin injection procedure occurs, or poor quality control. Maybe a mix of all of these.
The Werewolves, for example, often have webbed fingers due to the amount of flashing, while on the rest of the models, flashing is minimal. I have seen this on other minis within the range.
Flashing lines also appear is the weirdest of places. The aforementioned Werewolves, while having the standard mold/flash line running around the minis (leg side, torso side, arm side, shoulder and head, etc), they also have lines across the pectoralis majors/breast muscles.
Lastly, Mantic Games uses a plastic and resin mix that makes these minis beginner unfriendly. One cannot simply use a plastics glue (polystyrene cement), but rather super glue must be used. Hence, the minis' limbs must be pinned to ensure a strong join, so that the accidental dropping of the miniatures (and it happens to the best of us) does not see them break apart. You can tell the minis are made of a plastic-resin mix when they come as separate pieces, not attached to a sprue.
While all this sounds very critical of Mantic Games' choices in the production of some of their miniatures, and it is meant to, this is not to say that all their minis suffer the same problems. Their pure plastic ranges are really good examples of miniatures that are generally well made and beginner friendly.
