Oh gosh. Superman Returns, Brilliant. Ok, it's not quite as good as Superman The Movie, but it is utterly fantastic and oh so close.
Don't want to spoil it for anyone who hasn't seen it yet so I'm not going to say much about it. There's some beautiful moments, as expected from Bryan Singer, some brilliantly tense moments and some jaw dropping moments. Brandon Routh really does honour Superman, Clark and Christopher Reeve, Spacey is a crueler but recognisable Lex with everyone else doing a bang up job in their roles (I did find myself wishing Kate Bosworth would channel Margot Kidder but that probably wouldn't quite work for the film so what the heck), Parker Posey and James Marsden bringing a lot to roles that could've gotten lost.
If it has one flaw it's that it works so hard to successfully achieve the balancing act of introducing Superman to a new audience and respectfully following the Donner film (and there are so many wonderful riffs on that film, minor and major)) that it's not quite able to cut free. Funnily enough Singer's excellent X-Men film had a similar flaw, so much work was spent setting it all up that it was the 2nd film that took all the glory. Which is why as much as I absolutely loved Superman Returns I think the next one (please be another!) will be phenomenal.
