That was an excellent trailer. I've always been more of a Marvel guy but something as simple as showing Bruce witnessing Zod's eye beams slicing though that building was enough to start the stitching together in my mind of something resembling a cinematic universe and I was hyped.
I disagree with people like AngryJoe who are saying "look you guys, all along it was a plan to have so much destruction in MoS so that would set up the events in BvS." I think DC wasn't sure at all if MoS was going to be the start of their universe or not when making it since there is absolutely no universe building beyond your usual sequel set-up stuff. I would buy the "it was the plan all long" if there was something of the repercussions of the fight with Zod at the end of MoS. Instead it just rushes to Clark Kent happily working at what seems like a back-to-normal, fully functioning Daily Bugle. I think they have made lemonade from all the lemons (bad reactions to the carnage in MoS) by turning it into a major plot point in BvS. It actually makes me like MoS a bunch more. It would also be a good idea to point out and make it canon that Supes was still learning his powers at that point, maybe even have him struggle with having to learn to "hold back" so to speak.
