No spoiler (unless you haven't seen the trailer!) - I'll answer: Type of storyline, action, 3D vs 2D, duration, acting, music, after the credit

Rating: 10/10 (17 June 2013)

** Summary
If you're a fan you will most certainly love it. If you're not (like my date) you might find it too long and some action scenes being unnecessary. If you didn't like the previous Superman movies with the perfect, well shaved, invincible, emotionless Superman; you will probably like this one as it's really different!
** Duration & after the credit
The movie is 2 hours and 23 minutes and there is nothing after the credit so no need to wait for it. It really covers a huge part of Superman life. As you can see from the trailer, it spans from before his birth, then childhood, to the beginning of his adult life. You'll end up discovering some facts about Superman you probably didn't know (unless you read all the comic books)
** Type of storyline and TBC Sequel
Christopher Nolan (all new Batman movies, Inception) is the producer, Zach Snyder (300, Watchmen, Dawn of the Dead) is the director and David S. Goyer (new Batman movies, Blade, Call of Duty) the screenwriter. Therefore you can expect a storyline slightly darker than the usual Superman, with definitely more depth into the his character. That is the first time you really see his "human" side and some weaknesses not linked to kryptonite. However, listening to other people complaints: many found the movie being divided into two movies. The first one having a lot of depth with Superman being the unique being we all expect but with problems on his own. The second one having too many Kryptonians flying around looks more like a basic alien movie packed with over the top actions making the audience slightly frustrated not to have seen the usual "Invincible Superman stops the bad guys" (but hey, this is why there will be a Man of Steel 2 and probably a third one too and Superman appearing in a Justice League movie in the middle - TBC) The storyline is very linear but the flashbacks provides good insights into the past. A few goose spot on my arms at moments.
** Action scenes
The action scenes are good. As you can see from the trailer, some people can punch back Superman and it makes the action scenes extremely powerful and different from the usual "invincible" Superman who at some point will get weak from kryptonite exposure. The only problem for some people is that the action scenes are not spread across the movie evenly but mainly concentrated in one third of the movie. I caught my date checking her finger nails during some of the action scenes.
** 3D or 2D
The 3D is definitely not necessary. It adds a little bit of depth but this is definitely not a 3D movie (i.e.: nothing really popping out of the screen) The problem with 3D is that you lose some of the brightness.
** Acting
Henry Cavill is doing a great job (funny enough my date really enjoyed all of the topless scenes from him when he's not talking(?)) and the acting from Russell Crowe, Kevin Costner, Amy Adams, Laurence Fishburne, Diane Lane and Harry Lennix is impeccable.
** Music
It is composed by Hans Zimmer (Pirates of the Caribbean, Inception, new Batman movies, Gladiator, Sherlock Holmes, Frost/Nixon, Angels & Demons, The Da Vinci Code, The Last Samurai, Tears of the Sun, The Ring, Hannibal, The Thin Red Line, The Pledge, The Rock and so much more..). As expected from a guy who won more than 50 awards, it is really deep and impressive. The score is all brand new and doesn't sound like any previous scores.
