From Ain’t It Cool News, a positive review from someone who says he saw an early screening. The entire review has some spoilers, so I’ll post a spoiler-free excerpt here, and if you want to read the rest, you can visit the site.
Overall, it’s gloriously flash and fun, bold and hallucinogenic, all the while having a touch of grit, grain and gravity. What it is is seriously geeky, and was probably made to appeal to Superman fans first and foremost. This is because it takes its mythology seriously. It’s a long movie, but it’s never boring. It does return to the greatness of the first two movies. I thought this movie delivered on what I was after all along: a physical match for Superman.
