I agree and think the comparisons are more than a little unfair. Star Wars is further along in post and its marketing campaign, putting its trailer in front of a rabid live audience that paid to be there, while showing us semi-familiar stuff that's all been touched upon before the release of the trailer, and ending with comforting nostalgia of a familiar face.
The whole thing is calculated to bring warm fuzzies.
By contrast, the BvS teaser is our first official look and listen at anything substantive and it is intentionally designed to make you feel uneasy. There's provocative language and visuals like "false god", "terror", "lies", "corruption", "anger", "bleed", militarized bowing, people reaching out, etc. It decidedly is not attempting to make you feel warm and fuzzy feelings, but disorientate you with overlapping voice overs, etc.
I think it's a teaser that probably does need a preamble or mood-setting before experiencing, which is what the 15 minute IMAX event is about, rather than it being experienced cold and without context. Star Wars didn't do that... they warmed you up with Celebration.
So I'm guessing Snyder's presentation might go online at some point rather than waiting for the disc as a companion to the teaser for a movie a year out.
