I thought it was a really good effort, and it had some pretty good things going on. It had some horror comedy vibes too. The pacing is a bit off, especially in the first half, before things really kick off. The first half could have been edited better too.
I thought the lead and his best friend worked well, and things between them seemed really natural. There is a part where an urban legend is told and there's an animation to it, I actually really liked that. I think if they would have had a couple more stories like that, linked to (but not giving it away) the twist. I think it would have helped some of the long spaces at the begging.
The choice to film in black and white was a good one. I think when things kick off, the creature effects for the most part look good. And I think shooting in black and white probably helped with this. And when things get going, I did find it more enjoyable. It was just getting there.
