And Also, Lexs character is far more brilliant and complex than most people give him credit for. I would suggest listening to the Justice League universe podcast. They take time analysing every moment of the movie. The latest episode describes the scene with he and superman on the rooftop and the insights helped me appreciate the character and the movie that much more

On the death of superman i would suggest waiting to see what the filmakers have planned coming forward. These movies have been planned way ahead of time and i believe the decision to kill him off now will pay off. Great review and im glad you enjoyed the film
