I like each Lex Luthor portrayal for its own specific differences. Rosenbaum and Glover are the only bright spots on an otherwise dismal show. This is mainly based on the strength of their acting, and also due to the character development done for each. I enjoy Rosenbaum's Luthor because he portrays him in a very articulate and calculating manner. I felt indifferent about Shea's portrayal in Lois and Clark because he never seemed like a true threat. He more or less came across as an uppity wiener who belonged on Sex and the City. Hackman's portrayal is also one of my favorites because it masked undertones of an inherently sociopathic nature, but they painted it up to look all nice by '70s standards. Rather than being deadpan cold like Rosenbaum's character, Hackman's Luthor was a smartass who never showed an ounce of fear at a man who could squash him 36 ways to Sunday. Take for example, the scene at Luthor's lair. Superman breaks down the door, and rather than hiding, Luthor quips: "my attorney will be in contact with you about the door." If I had a metahuman demigod shatter a steel door coming after me, I'd have pissed myself before he even looked at me. Lex just spends time hanging out with Superman before he tricks him into dropping the rock on himself. The only flaw is that they saddled Lex with absolute morons as sidekicks. But if you ask me, that's the only way they could make it so Superman could escape the clutches of someone who is leagues smarter than he is. I'd like to see Spacey's Luthor be a marriage of Rosenbaum, Brown's, and Hackman's performance and just play off the strengths of each.
