I enjoyed it.
I watched it without knowing anything about it, other than that I'm a fan of Peele's stuff. It was very different to his other films (although with some slight similarities) and didn't go in the direction I expected
Saw it a few weeks ago and thought it was very good. The trailers that were shown for months at cinema gave a slightly false impression (to me) of what to expect. It is a bit off the wall, bit of a cross between tremors and close encounters as the type of film to expect (not saying it is as good as either of those)
