After reading your comment, I took a peek at the /startrek subreddit - notorious for its enforced-positive bias and heavy-handed modding (was temp. banned on a few occasions for the most innocuous criticisms / jabs). I had a look at the trailer thread and Jesus Christ, it was absolutely savaged. One commenter mentioned they were shocked the mods were allowing the pile-on (ditto!).
Even the insufferable Trekmovie.com comments section (someone there doesn't like me as not a single post I attempted to make ever made it through review, lol), is leaning negative.
As far as this place - yes - there are a handful of posters who will defend almost anything with Star Trek slapped on it, but I'd hazard a guess the reaction will lean negative here too.
You've also got to remember there's a lot of apathy / disinterest. I'd say most regular posters who originally came here to discuss Trek spend more time discussing other subjects and can't be bothered with gatekeeping.
