Every Trekie pretty much agrees that the second Star Trek movie — “The Wrath of Khan” — is the best of the bunch. Who can forget Ricardo Montalban as the superhuman Khan, locked in a final showdown with Kirk and the Enterprise?  Now, Diamond Select is coming out with a commemorative Wrath of Kahn USS Enterprise, 16” of plastic final frontier, complete with a fancy new paint job. It’s also fitted with flashing deep space lights and sound effects from the movie.
