It is a very impressive figure. One of my favorite things is the weathering on the coat, a small detail, but the quality of wear and tear HT's able to mimic in production figures is really improving this year and it's a detail that really sells the realism in these things. One thing that hurt the ALIENS marines was the armor and uniforms look brand new and perfect, now you get a figure like John Connor and the leather coat's beat up, the camo pants look all faint and worn.
The coat on DX Joker really is the big difference. If they'd just packed in that coat alone and we swapped it onto our v1-BR bashes, that figure would look just as good, the proper tailoring and color of the new coat really completes selling a figure as Heath Ledger's Joker.
