Superman Returns had its issues, but I adored the half modern/half classic art deco look that movie gave Metropolis.
It was shot in Sydney and I recognise a lot of the locations. The car scene with Parker Posey was shot in Martin Place where I used to work. Whenever I'd come to work in the morning I thought to myself "Superman was here" so I have nothing but love for that movie.
In those terms, I think the movie ending for Watchmen is a LOT better. Not that I'm gonna start giving Alan Moore a hard time for his writing but talk about a convoluted ending to Wathcmen.
I agree that the movie ending makes more sense (and the guys that made the movie should be commended for making that change) but the comic book ending didn't confuse me. I read it as an adult though (only a few years ago) and not as a kid. If I read it when I was younger I could see it confusing me. That said, it's not like I can tell you word for word exactly what happened. It's one of those things that made sense while I was reading it but I don't recall every single detail about it. I've been meaning to reread it to pinpoint what was confusing about it.
