Yup, I can say that Kate and Brandon had chemistry. I really think they did.
Just because you think something is so doesn't make it fact. It's your honest opinion. That's fine. But a lot of us like the film (acting, writing, plot, and all). Does it have flaws? Yeah, what movie doesn't? But I, personally, love what Bryan Singer did with this flick. I feel he successfully brought the Man of Steel back on screen and back in the public eye.
Now, I'm looking forward to his take on the sequel, which he has promised to be "Wrath of Khan"-esque and to bring a lot from contemporary comics.
And, on a side note, I think Hayden Christensen and Nathalie Portman were great in the Star Wars prequels.
