The new "Super 8" movie.?

Has anyone seen this movie yet? If so what is the "thing" in the movie
that is causing all the trouble? I'm not going to be able to see it
cause I don't have the money, nor do I want to wait 6 months for the
movie to come out on DVD.

So again what is the monster thing, or whatever it is? If you can,
please provide a picture of it or something.
Oh an Note:

I can't see it becasue I don't have the "MONEY" to go see it. So don't
suggest by telling me I should go see it, if I can't afford it.
