To make a decent horror movie you don't actually need a decent budget. You need a decent script, you need decent actors and - more than anything else - you need a decent talent behind the camera who know how to utilise all the tricks of cinema to generate and maintain suspence, tension, mood, atmosphere and - above all - tension.
Pumpkins has none of these things.
What starts with a set-up that might have worked if played as a comedy but is instead played dead straight, proceeds to follow up the lack of jokes with a lack of anything you want from a horror movie. It doesn't even have a decent ending - it just ends with no sense of resolution or even a final confrontation. Another character gets killed off, many more still alive, we get a few shots of night time roads and then ... it ends. No idea what the heck that was supposed to be - the only thing I can guess at is that they were shooting it in order and then ran out of budget so just stopped.
There isn't a single redeeming feature to this film. Utterly astonishing in quite how bad it is.
If you are looking for low budget horror, everyone involved has made better movies - search out their IMDb profiles and find something better there. Literally anything will do; this is the career low point of everyone involved.
