Yes it is very cool!!! Can't wait to get this!!!!
Its a toy, its just never going to be 100% accurate especially with head sculpts. Even the best most amazing head sculpts by companies or custom artists still dont achieve 100% accuracy because its made by hand and just very difficult to sculpt things that 100% life-like human face. Might be the hardest thing to do in art & sculpting. Think about sculpture outside of the toy realm, there aren't many artists out there or over history that have sculpted human faces that look 100% like a certain person. Some come very close, but its really difficult.
But whatever, i guess we all have our own views about this stuff. I personally have always been very happy with HTs when it comes to their Batman stuff. Its more about collecting the character & toys for me. If you want 100% accuracy you need to collect 1:1 replicas or real movie props.
