The more times I've watched Star Trek III, the more I've realized why I like Kruge and why stands out to me. In comparison to the others, he wasn't a a bitter enemy looking for revenge (Khan, Nero) a mysterious entity doing damage to Earth (V'Ger, Whale Probe), or even a damaged individual with tragedy in their past going to extreme measures (Shinzon, Soran). He's just a heartless dickhead who wants Genesis Device for its own sake. Its kind of nice to see a villain who you can just watch be an asshole without having to go into some deep backstory.
