I always love this kind of subject matter, and plan to get a set of these. The deformed *brothers* is an especially cool idea, but this one could have been done better, but this one is not bad.
From what I've read, these are hollow vinyl, and the sculpts don't seem to be lacking in detail in certain areas, but overall look to be worth getting.
