To me, this only emphasizes how badly the Star Trek license needs to be taken from Kre-O and given to Lego, because if there were a silver lining to a Big Bang Theory set, it ought to be that you could re-enact “Priceline Negotiator” ads with Cuoco. Lack of Lego Shatner is a crime for many reasons – the only Kreon Kirk is the Chris Pine version – and that is just one.
