Bullet points:
Good - using the Williams score, original titles style and Brando voice-over for the start sequence: all good calls;
Bad - Kate Bosworth: bad casting. No charisma. Never for a second convinced me that she was a spunky reporter;
Good - Brandon Routh: I thought nobody could fill Christopher Reeve's shoes, but this lad does well;
Bad - costume. They got it right in the 70s movies. The effect of darkening the colours, reducing the shield size and dropping the waistline of the trunks is well-known to clothes designers - it makes the wearer look tall and thin. Reeve looked broad and imposing.
Good - saving the shuttle/plane, and dealing with the Metropolis "quake";
Bad - not enough of that stuff;
Good - Spacey's Luthor. Clearly grown from the same seeds as Hackman's, but much more definitely a villain. I believed that this Luthor was fundamentally evil;
Bad - Kitty Kowalski. What an underwhelming character. Miss Tesmacher-lite;
Good - Richard White - a potentially interesting new character, to sit in a potentially very interesting group dynamic;
Bad - Tristan Lake Lebeau. Superman's son is autistic? Sorry, kid - you were rubbish.
Good - tweaking the franchise back into life again;
Bad - forgetting that Superman isn't Batman. Superman is supposed to be light. Superman is supposed to be FUN! Don't take it so seriously, next time!
