While i don't feel MOS will be the best superhero film we've seen, i do believe 2 things.
1. It will be the best film interpretation of Superman
2. It will contain the best tone of any comic book film. What i mean is, Zack and co. will have created the perfect balance between realism and fantastical.
I love Nolan's series, i hold it in high regards. However, i feel Nolan went a bit too realistic in some aspects, when it comes to the three films. Because his series was rooted in such a realistic surrounding, we didn't get to have fantastic villains like Riddler. I still feel The Riddler could have been portrayed as a psychotic, destruction hungry man, who with each clue, would have a public bombing if his riddle wasn't solved.
I'm going off a bit topic, but i'm hoping the next reboot of Batman has a few more fantastical elements thrown in. The reboot will have to if it wants to be part of a Justice League Universe.
Just had to get that out of my head.
