Terrible acting.

Especially the asian 'Karen'.

Lazy script. And adding Amityville to the title was more of a hindrance than a help as totally unrelated to any other of the many films using the name.

The news reports were a distraction and the actor they chose was beyond cringe.

Within the first few seconds there is an explosion that is some of the worst cheap Chroma Key overlay I have seen outside a joke mobile app. That really let me know that what was coming would be very poor. If they let that through as acceptable then they had really low quality control.

Pointless attempts at drama with the cop and his 'kid' ! Really did NOT work at all. The interaction and dialogue is some of the worst I've seen in an long time. Think "The Room" level bad.

Couple of attempts at bloody practical FX work ok. But the red sky and acid rain looked so cheap it hurt. Ha ha

And why would anyone hear the radio say "acid rain, stay indoors" and 5hen instantly get out and then when feel it burns just stand there instead of getting into the car....squirming with more bad acting. That bit should have been cut, there was no blood or any makeup on him at all, melting gags are the easiest to do. . When he stands up and you see through the car window and he has a little blood it works so much better. But you were still in shock at the awful scene seconds before to care.

Zero tension.

A serial killer added to try and add some tension. Again fails.

Star for at least trying.

It s tough to get a film going and get a release so credit for that and hopefully they will all learn valuable lessons from their failures. Micro budget doesn't have to mean a total crapfest.

The ending. Well. As daft as the rest of it.
