The killer clowns house we got didn't even cover the whole movie. There were little parts and scenes missing. There were gags and jokes from the movie missing here and there.
Yeah It would technically be like how they did Halloween again last year, but, the difference is that killer clowns had more stuff cut from the first house.
Even if they recreate the parade from the movie alone it would be awesome. Make the part in the ship longer. Add more of the carnival.
