I have to agree.
What I liked about the first Mass Effect is that it at least paid half-hearted lip service to Clarke/Asimov style scifi, interwoven in the usual space opera bling, but after the first game I can't help but to get the feeling that somebody is on a mission to root out any such things to only leave the Michael Bay elements remaining.
I realise that this is a minority opinion, but there you go.
As for the extended version of the trailer; It feels rather unfocused -- flash cuts from several previous teasers, just the profitable "visceral" and "compelling" stuff, I suppose, which taken out of context adds nothing but padding.
