Few problems i have with it:
1) as said before, they are completely unfazed by splitting humans in half/beheadings/other gruesome ways of ending life. I hope there'll be at least some reasoning for that.
2) fight was kinda comedic gore-y, and kinda meh imo. This got comedy tag, so i guess it might be fine later on.
My biggest gripe: IT'S UNREALISTIC. They wouldn't drive stock forklift into battle. In a world where OSHA guys would be more terrified of their coworkers than the demon army and no way to realistically enforce anything, this forklift would be something between killdozer and hedgehog tank from the Ukraine front. Possibly accompanied with a dump truck converted into a rocket launcher and few other vehicles actually all of the on-site vehicles would be converted. Depending on the situation, one might even have OSHA guy tied in front.
