Whoa, I seem to have struck a vein of watchable horror movies on Tubi.

This Australian teen scream is actually pretty creepy for the lightweight genre, and in terms of story it veers a few degrees off the normal path for a teens-messing-with-the-supernatural flick.

A group of Australian teens conduct a ritual using a corpse's hand and find it possesses them. So what do they do? They party and have fun with it, laughing as each in turn's eyes go wide and they start gibbering and lashing out, until things start to turn a little too scary. From there on in it handles reasonably standard group-of-kids-dogged-by-a-supernatural-force tropes with decent enough atmosphere and acting to make it stand out a little from the crowd, and be more watchable than you'd expect.
