I gave it a "C", since "C" is average and I felt it was a very average trailer that happened to be about the greatest character in comics history. It was your typical muted colored, darkly serious, pretentious type trailer. I would have given it a B but the Jonathan Kent thing irked me too much so I went with a C. Best part was the flight takeoff and him circling the Earth, which was also the shot that reminded the most of the Reeve series.
I also have to admit I love Lois holding his hand. I think Amy Adams' Lois will be something new and really good.
