I'll say this. I think the content of what we see in the film looks absolutely fine (and no, there's nothing "Unlike" Star Trek about it.) I think the trailer itself is maybe what's causing problems for some people. As a matter of I think it's just slightly in cohesive (or something similar.) I think when the full trailer comes out down the line that you'll see some opinions shift.
Wil Wheaton implied on his Twitter that it looked like a Generic Sci-Fi Action film with Trek uniforms. Well, so did most Trek film trailers. The only reason they were "familiar" to Trekkies then is because they kept following the same formulas and featured an ensemble cast of people that people already associated with Star Trek.
However, I think it's absolutely 110% silly to start casting a movie out because of a 1 minute trailer.
