I wanted to step in and say my piece, I saw the conjuring and it blended in with sinister and insidious as all films that had the occasional moment, but nothing that really distinguished them from each other.
If you enjoyed the other films mentioned then give it a go.
Otherwise wait for an inevitable t.v showing, then at least yo haven't spent anything.
