Reeve had the personality, charm, and presence of Superman. There's a reason why there's only been one other actor besides Cavill to fill his shoes.
That being said, the movies themselves are accomplishments given that they are first superhero blockbusters-and a lot of fun to boot.
But in the wake of the more dramatic narrative style of introspective superhero movies, Spider-Man 2, Batman Begins, Iron Man, they come a bit short. Since he likes it better than Superman: TM and the other reviewer liked it as much as TDK, I think we're in to something awesome, with a few flaws. Plus, I think MOS has unrealistic expectations that Batman Begins didn't have to live up to.
As far as Adams as Lane, if she's the weakest aspect of the film, it would be a testament to how strong the film and cast is overall.
