I've heard it before, but I still don't get it.
As for SR, I watched it again last weekend, and as much as I loved it before, it now seems almost painfully small and limited in scope compared to what we're seeing from MOS. I can kind of understand now why so many were underwhelmed by it, and why people are so much more excited by what they're seeing from MOS.
I agree. From what we have seen Superman Returns looks very anemic compared to the Man of Steel. I still like Superman Returns....but it could have been better.
