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.
If Singer had burst out of the gates with guns blazing then I'm sure things would have been fine.
Part 2 would have probably departed from Donner's vision slightly. I think he was waiting for the sequel to really let loose similar to "X-men 2"
He was just building on what was established before THEN he'd serve the main course(Part 2)
