I know this is not a time but a few days ago i saw MOS again and came up with this Article about How this movie is a great movie and have watched it 3-4 times after that especially During my Semester Exam, Anyhow these are few points that shows why this Movie is great and a bit overlooked or whatever.
1)
STORY
The First and Foremost thing about this movie was its Story and i thought it was a great story. it started with a beautiful but soon to be doomed krypton, then in Earth the Build up was great with Clark acclimatizing to the Earth's Atmosphere with Zod seeking revenge and Come to earth and after 100 minute mark, it was all Action.
2)
ACTION SEQUENCE
The Main reason for downfall of 'Superman Returns' was the scarcity of action in that movie. there was a great scene of saving a jet Airliner, Lifting a Half-Ship & even Lifting a Small Continent of krypton. but We fans were hoping for a one on one fight with a competent foe of same kind and that's exactly what we got in Man Of Steel, first with Faora & Zod's henchmen against Superman and wasn't it great, that sequence till the last scene of the movie including fight with ZOD was an Adventure for Action Lovers.
3)
GENERAL ZOD
In General Zod, Superman got the nemesis what he deserved and also fanboys deserved for many years, He was great in the sense that he had his motives to rebuild Krypton and thus was the reason he was born. He found Earth and eventually Kal-El. He wanted a similar Planet to terraform the krypton and wanted to Kill Superman when he came to know that codex is in his blood & Michael Shannon as Zod Nailed it in all departments and impressive.
4)
MUSIC/SOUNDTRACK/SCORE
When it Comes to give score to a movie there isn't any better name than the one & one only 'Hans Zimmer' and when u listen to the score of man of steel, you will feel it. its one of the best music/score, it gives a meaning to each and every scene. In My view its the best score after The Dark knight, X Men: First Class & The Avengers in terms of CBMs.
So These are the things that make this movie A Spectacle and A Must Watch.
