Watched "Send Help" it with my wife (not a horror fan) and we both loved it
I'm a sucker for Sam Raimi, so I was already hyped going into this movie and it was everything I'd hoped for. Rachel McAdams is a fantastic lead, teetering between sympathetic and unhinged, and Raimi adds a lot of his signature camera work and comedy making this a "horror" movie with broad appeal.
I watched this with my wife last night, who is, at best, "horror tolerant", and she loved it too.
The horror elements are fairly light, other than a few scenes of violence and body horror, but, as Raimi often does, there's comedy mixed in to turn the horrible into the hilarious. There were definitely scenes where my wife had to turn away while I was cracking up like a maniac.
My only critique is that Bruce Campbell didn't make an appearance.
all in all 8/10 - really fun movie, well directed, well acted, with enough horror to keep a die hard fan satisfied, but also approachable for more casual viewers.
It's included on Hulu right now
