The amount of time it took me to think of that title pun is the same time it took the filmmakers to work on this movie.
An estranged family inherits their dead mothers campground (the land was a cornfield that never could grow corn *spoooooky*
One sister slept with the others husband long ago and now they hate each other. Much to one's dismay, they decide to try and fix the camp up and make a go of it. Unfortunately there happens to be two murderous scarecrows on the grounds.
Typical of most of today's low budget horror from the UK, Amityville Scarecrow looks nice. Lighting and cinematography are competent. The actors are mostly decent, with the only exception being the sister Mary - her shrill voice and angry attitude make you want the scarecrow to off her asap. Music and sound design are also pretty poor, I would be surprised if the music wasn't all free stock tracks, and the audio in several scenes has an extremely loud sound floor of wind, likely to mask that the audio was recorded with that same noise I would guess.
How about what we are here for: the horror content? The scarecrow costume is basically a higher end Halloween costume, but it looks decent. The kills however are uniformly awful. Most kills are offscreen and we get a body with a dribble of blood from its mouth.
If they had spent some money on even rudimentary special effects and provided some gore, Amityville Scarecrow could have been a passable slasher flick, instead, we get another in the ever growing long list of terrible Amityville flops.
Oh, and how does this relate to Amityville you ask? Well it seems that the High Hopes house was located on the land and torn down to build this campground. How Long Island has mysteriously transported to the English countryside is not mentioned.
