I thought it looked... wow, it was just really, really boring to me. The trailer implying that it's an in-universe continuation of the original (and no, it doesn't matter one iota what anyone else said; the trailer directly implied it) somehow just made it worse.
For the trailer itself, the very first scene they showed really set the mood. It lacked anything that made the similar scene in the original movie so good, basically turning into a bathroom joke (and yes, I place projectile vomiting in the same category as pissing and shitting).
Considering that they almost always put some of the most humorous bits into the trailers, and this one was pretty devoid of any real sense of humor (certainly any humor on par with the original), says a lot, too.
Very disappointing. Especially given my obsessive love of
Kate McKinnon. (Incidentally, it's a real shame
that character wasn't her character in the movie.)
