I liked Lana and thought she and Clark had more chemistry then Louis and Clerk so that is in the win pile right there. With Louis I got the idea that she put up with Clark but loved Superman. With Lana I got the idea that she liked Superman okay but Clark was the one she really enjoyed spending time with and she respected him so the relationship came off feeling a lot more real then the Louis and Superman relationship. Lana didn't feel like she was just a schoolgirl with a crush but a real adult person.
Oh and the film has the best line in movie history.
"I ask you to kill Superman and you can't even do this one simple thing."
Yeah it's an underrated movie.
