So now I've had some time to re watch it a ridiculous amount of time, fully digest it and figure out how I feel about it, here's a summation of my reaction;
My reaction:
Was already kind of sobbing in anticipation. Cried during the first 10 viewings, then had to go to bed and get up really early for work (so little sleep I slept through my alarm and was late

!). Have watched it during my lunch break on repeat and everytime I went to the bathroom today
I absolutely love it. It is everything I ever wanted it to be
The score is fantastic. The emotional piano piece at the beginning goes so well with the beautiful visuals and heart felt goodbye, and then when it kicks in it has a really epic, inspiring vibe that feels absolutely right for Superman.
There is nothing about the trailer I don't love.
The look of Krypton. Russel Crowe's delivery and his simple line 'How'. The exchange between JK and CK (which reminds me of a similar exchange from Secret Origins that David Goyer said inspired him when writing the film), the shots of the fortress, Lois's line about him being a guardian angel, Clark ushering people to safety while chaos rains down around them, coming out of the FOS in the suit, Jor-el's line (from All Star Superman) again, mouth watering action shots that refuse to give anything away in time to adrenaline building drum beats, Zod screaming like a badass, a quick glimpse of Lexcorp in the Metropolis skyline, a gorgeous shot of the cape in motion, Superspeeding away from gunfire, shirtless hairy Clark (yum), close up shots of Supes flying, a great look at the chemistry and unspoken attraction between Lois and Supes, the line about the 's' being a symbol for hope (taken from Birthright), Superman smiling, a bit of light tongue in cheek humour by only teasing the name Superman...
And finally, a frustratingly small clip of what could very well be a fight scene like nothing we have ever seen before! (I mean, have we ever seen a superspeed, in flight punch up before?

)
Did I miss anything?
Seriously, we couldn't have asked for a better trailer as fans.
I just have zero clue how the GA will see it!
