A house would at least be slightly better. At least they can be more faithful to the source material as there's more to work with.
For instance, they can have a scene where all of the original fans are angrily commenting and disliking on the trailer, a scene with Chris Hemsworth saying how he's the only tolerable aspect of the movie, a scene with Patti screaming "AWWW HEEEEEEAALLLL NAAAAWWWW!!!!" and slapping the crap out of the guests, a scene with McCarthy falling on her butt while busting a ghost, and have the final scene with Rowan getting shot in the crotch with the female GBs' proton packs. (Spoiled it so you don't have to waste you money.
). Then have the final, FINAL scene be the angry people on the Internet moaning it's not bombing as hard as they hoped. SO MUCH TO WORK WITH FOR A HOUSE!
The best part if this was a house? It'd be funnier and better than This is the End!
