Bug opens in a few weeks (May 25th) and it's been generating a lot of discussion about what sort of movie it actually is.
The trailer is here, so you can see how they're marketing it.
From that, (I'm assuming you watched it), it looks like it might be a motel movie like Vacancy or Identity, or a plague movie like 28 Days Later which, we'll digress for a moment to mention, saw its sequel 28 Weeks Later have a pretty decent opening over the weekend.
They're also pushing that it's from the director of The Exorcist (William Friedkin), which seems to indicate they want pretty badly for us to associate it with "horror."
However, they don't go out of their way to mention that it's based on an Off-Broadway play (which might be why it looks like it's set in one room - easy to stage!) or that said play is a psychological drama about paranoia and guilt.
Soooo....it looks like it's going to be pretty interesting, but it looks like anyone going into it expecting cats to be leaping out of closets or monsters or even masked hack-masters will probably be disappointed.
Monsterfest is preparing you. It's a horror film in the way that Repulsion is a horror film, one of those internal struggle, wrestling-with-inner-demons type of flicks, and those aint the type of demons you call in a priest for.
You have been warned.
