Seeing it again (and even the first time), I had to chuckle a bit at Jor-El's "You can save all of them" line to Kal. Yeah... about that, dad. It's a nice sentiment, but I think you meant "most of them". Some of them are going to get crushed pretty badly.
On a planet with a population of seven billion threatened with complete extinction, if ten thousand died he saved 99.9999% of them. You're selling it pretty short by describing it merely as "most of them."
